Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, an electrocardiogram recording method is proposed, which can be applied to an electrocardiogram recorder, and the present embodiment is exemplified as being applied to an electrocardiogram recorder. The electrocardiogram recording method specifically comprises the following steps:
The lead is that electrodes are placed at different parts of a human body and are connected with the anode and the cathode of an amplifier of an electrocardiogram recording machine through lead wires, and the placing positions of the electrodes at different parts of the human body and the connection mode of the electrodes and the amplifier are called as the lead; the left atrial lead refers to the placement position of an electrode at the left atrial part of a human body and the connection mode of the electrode and an amplifier, and the right atrial lead refers to the placement position of the electrode at the right atrial part of the human body and the connection mode of the electrode and the amplifier; the left atrial electrocardiogram data and the right atrial electrocardiogram data are related data of electrocardiograms acquired by a left atrial lead and a right atrial lead respectively. In one embodiment, the left atrial electrocardiogram data and the right atrial electrocardiogram data are acquired respectively according to different left and right atrial leads, the left atrial lead and the right atrial lead can be acquired according to the selection of a user, and the electrocardiogram data acquired by the different leads are different.
And 104, respectively carrying out trend analysis on the left atrial electrocardiogram data and the right atrial electrocardiogram data, and marking electrocardiogram fragments corresponding to abnormal trends when abnormal trends are obtained through analysis.
The trend analysis refers to comparing and analyzing the acquired left and right atrial electrocardiogram data with left and right atrial electrocardiogram data of the same type of indexes acquired at different periods, so as to determine the conditions of the left and right atria and the change rule of the electrocardiogram. Trend analysis may include: analyzing heart rate trend, ST-segment displacement trend and arrhythmia event frequency trend; the abnormal trend refers to a change trend different from the conventional change trend in the change trend of the electrocardiogram data; the labeling means labeling the electrocardiogram section corresponding to the abnormal trend, for example, labeling the electrocardiogram section corresponding to the abnormal trend, or labeling the electrocardiogram section corresponding to the abnormal trend with color, so that the section where the abnormal trend is observed in the electrocardiogram data can be labeled according to the color. In one embodiment, electrocardiogram segments corresponding to different abnormal trends can be marked respectively according to different abnormal attributes. Assuming that arrhythmia trend analysis is performed on the left atrial electrocardiogram data and the right atrial electrocardiogram data respectively, that is, the change rule of the heart rhythm in the left atrial electrocardiogram data and the right atrial electrocardiogram data is analyzed, when arrhythmia trend (i.e., abnormal trend) in the change rule of the heart rhythm is detected, the electrocardiogram segments corresponding to the arrhythmia trend are marked, and arrhythmia trends with different attributes can be distinguished by using different marks.
And 106, respectively extracting a left atrium abnormal electrocardiogram fragment corresponding to the left atrium and a right atrium abnormal electrocardiogram fragment corresponding to the right atrium according to the marking result.
The marking result refers to a result obtained by marking the electrocardiogram fragment corresponding to the abnormal trend. Since the abnormal trend is obtained by trend analysis of the left atrial electrocardiogram data and the right atrial electrocardiogram data, the abnormal trend can respectively correspond to the left atrial electrocardiogram fragment and the right atrial electrocardiogram fragment, so that the left atrial electrocardiogram fragment and the right atrial electrocardiogram fragment are respectively marked to obtain respectively marked results. In one embodiment, the electrocardiogram fragments marked as abnormal in the left atrial electrocardiogram data and the electrocardiogram fragments marked as the same abnormal in the right atrial electrocardiogram data can be extracted respectively according to the result of the respective marking. And by analogy, extracting corresponding left atrial electrocardiogram fragments and right atrial electrocardiogram fragments marked as the same abnormity according to the marking result.
And step 108, determining the abnormal type according to the abnormal electrocardiogram fragment of the left atrium and the abnormal electrocardiogram fragment of the right atrium.
The abnormal type refers to a category to which the abnormal trend belongs, and the abnormal type can be set to be various according to needs. In one embodiment, assuming that the abnormality types are set to three types as required, the three abnormality types can be obtained from the three different cases of the abnormal electrocardiogram fragments of the left and right atria, respectively. For example, when the condition between the abnormal electrocardiogram sections of the left atrium and the right atrium is a first condition, determining that the first condition corresponds to a first abnormal type of the three abnormal types; when the condition between the abnormal electrocardiogram fragments of the left atrium and the right atrium is a second condition, determining that the second condition corresponds to a second abnormal type in the three abnormal types; when the condition between the abnormal electrocardiogram fragments of the left atrium and the right atrium is a third condition, determining that the third condition corresponds to a third abnormal type in the three abnormal types; the type of abnormality can be determined from the left atrial abnormal electrocardiogram fragment and the right atrial abnormal electrocardiogram fragment.
By performing trend analysis on the electrocardiogram data of the left atrium and the right atrium, marking electrocardiogram fragments corresponding to abnormal trends obtained by analysis, and determining abnormal types according to the marked abnormal electrocardiogram fragments of the left atrium and the marked abnormal electrocardiogram fragments of the right atrium, the priority judgment of the left atrial wave and the right atrial wave can be accurately realized.
As shown in fig. 2, in one embodiment, the determining the type of abnormality from the left atrial abnormal electrocardiogram fragment and the right atrial abnormal electrocardiogram fragment comprises:
The preset waveform refers to waveforms corresponding to preset left and right atrial abnormal electrocardiogram fragments, for example: p-waves and A-waves; the marking result is obtained after marking the electrocardiogram fragment corresponding to the abnormal trend, and the marking result comprises the marking starting time; the marking start time is a time point at which the marking operation of the electrocardiogram section corresponding to the abnormal trend is started. In one embodiment, the preset waveform may be preset according to the user's requirement, for example, when the user needs to observe the P-wave of the abnormal electrocardiogram segment of the left and right atria, the P-wave may be set as the preset waveform.
And 204, determining the type of the abnormity according to the preset waveform and the mark starting time.
The abnormal type refers to a category to which the abnormal trend belongs, and the abnormal type can be set to be various according to the requirements of users. In one embodiment, the corresponding anomaly type may be determined from a relationship between a preset waveform and a marker start time. For example, it is assumed that the abnormality types are set to three types, which correspond to three relationships between the preset waveform and the marker start time, respectively. When the relation between the preset waveform and the mark starting time is a first relation of the three relations, determining that the first relation corresponds to a first abnormal type of the three abnormal types; when the relationship between the preset waveform and the mark starting time is a second relationship of the three relationships, determining that the second relationship corresponds to a second abnormal type of the three abnormal types; and when the relationship between the preset waveform and the mark start time is a third relationship of the three relationships, determining that the third relationship corresponds to a third abnormality type of the three abnormality types. According to the relation between the preset waveform and the mark starting time, the abnormal type can be determined according to different relations between the preset waveform and the mark starting time, so that the determined abnormal type is more accurate, and the accurate judgment on the left atrial wave and the right atrial wave in priority is realized.
As shown in fig. 3, in an embodiment, the determining the type of the abnormality according to the preset waveform and the mark start time includes:
The occurrence time refers to the time point when the preset waveform appears in each left and right atrial abnormal electrocardiogram segment, and the occurrence sequence refers to the sequence of the preset waveform appearing in each left and right abnormal electrocardiogram segment. After marking the start time, acquiring the occurrence time of the preset waveform in each of the abnormal electrocardiogram fragments of the left atrium and the right atrium, because the preset waveform may occur in each of the abnormal electrocardiogram fragments of the left atrium and the right atrium; in each of the left and right atrial abnormal electrocardiogram fragments, the occurrence times of the preset waveforms may be the same or different, so that the obtained occurrence times need to be sorted in time sequence, and the occurrence sequence of the preset waveforms in all the abnormal electrocardiogram fragments is obtained according to the sorting, so that whether the preset waveforms are firstly present in the left atrial abnormal electrocardiogram fragment or the right atrial abnormal electrocardiogram fragment can be judged according to the occurrence sequence.
The first abnormal type refers to a category to which a preset first abnormal trend belongs, and the first abnormal type corresponds to a condition of a preset waveform in the abnormal electrocardiogram section of the left atrium and the right atrium, that is, the first abnormal type corresponds to a condition that the preset waveform appears in the abnormal electrocardiogram section of the left atrium first. As shown in fig. 4, in one embodiment, when the preset waveform appears in the abnormal left atrial electrocardiogram fragment first, it may be determined that an abnormal trend appears in the abnormal left atrial electrocardiogram fragment first, and the category to which the abnormal trend belongs may be determined as the first abnormal type.
The second abnormal type is a category to which a preset second abnormal trend belongs, and the second abnormal type corresponds to a condition of a preset waveform in the abnormal electrocardiogram fragment of the left atrium and the right atrium, that is, the second abnormal type corresponds to a condition that the preset waveform appears in the abnormal electrocardiogram fragment of the right atrium first. As shown in fig. 5, in one embodiment, when the preset waveform first appears in the right atrial abnormal electrocardiogram fragment, it may be determined that an abnormal trend first appears in the right atrial abnormal electrocardiogram fragment, and the category to which the abnormal trend belongs may be determined as the second abnormal type.
And 310, when the preset waveforms simultaneously appear, determining that the abnormal left atrium electrocardiogram section and the abnormal right atrium electrocardiogram section are of a third abnormal type.
The third abnormal type is a category to which a preset third abnormal trend belongs, and the third abnormal type corresponds to a condition of a preset waveform in the abnormal left atrium and the abnormal right atrium electrocardiogram sections, that is, the third abnormal type corresponds to a condition that the preset waveform appears in the abnormal left atrium electrocardiogram section and the abnormal right atrium section at the same time. In one embodiment, when the preset waveform is simultaneously present in the left atrial abnormal electrocardiogram section and the right atrial abnormal electrocardiogram section, it may be determined that the abnormal trend is simultaneously present in the left and right atrial abnormal electrocardiogram sections, and the category to which the abnormal trend belongs may be determined as the third abnormal type. The abnormal electrocardiogram fragment with the first occurrence of the preset waveform is obtained by judging the occurrence sequence of the preset waveform in all the abnormal electrocardiogram fragments, so that the abnormal trend of the abnormal electrocardiogram fragment with the first occurrence of the preset waveform can be judged, the abnormal trend of the abnormal electrocardiogram fragment with the right atrium can be judged, or the abnormal trend of the abnormal electrocardiogram fragments with the left atrium and the right atrium can be judged simultaneously, and the category of the abnormal trend can be further determined, namely, the abnormal type can be determined and obtained for judging the priority of the left atrial wave and the right atrial wave.
As shown in FIG. 6, in one embodiment, the trend analysis includes: heart rate trend analysis, ST-segment shift trend analysis and arrhythmia event frequency trend analysis. The analysis of the heart rate trend refers to the analysis of the change of the heart rate regularly, the analysis of the ST-segment shift trend refers to the analysis of the change of the ST-segment shift regularly, and the analysis of the trend of the arrhythmia time attack frequency refers to the analysis of the change of the arrhythmia time attack frequency regularly. By analyzing the electrocardiogram data of the left atrium and the right atrium, the change rule of the heart rate, the change rule of ST-segment displacement and the change rule of the time attack frequency of arrhythmia can be obtained. The trend analysis is performed on the left atrial electrocardiogram data and the right atrial electrocardiogram data respectively, and when abnormal trends are obtained through analysis, the electrocardiogram fragment corresponding to the abnormal trends is marked, including:
The trend time period is a time difference between a start time and an end time when an abnormal trend appears in the electrocardiogram data of the left atrium and the right atrium. Since the abnormal trend is different from the conventional trend in the trend of the electrocardiogram data of the left atrium and the right atrium, the analyzed abnormal trend corresponds to the abnormal trend starting time and the abnormal trend ending time, and the time difference between the abnormal trend starting time and the abnormal trend ending time can be used as the trend time period of the abnormal trend for marking the electrocardiogram segment corresponding to the abnormal trend subsequently.
And step 604, extracting electrocardiogram fragments which are in the same time period as the trend time period from all the left atrial electrocardiogram data and the right atrial electrocardiogram data, and marking the electrocardiogram fragments.
The same time period as the trend time period refers to a time period equal to both the start time and the end time of the trend time period. Since the left atrial electrocardiogram data and the right atrial electrocardiogram data are acquired simultaneously, and the electrocardiogram fragment corresponding to the abnormal trend can be the left atrial electrocardiogram fragment and the right atrial electrocardiogram fragment, all the electrocardiogram fragments need to be marked simultaneously. In one embodiment, all the extracted electrocardiogram segments can be marked by respectively acquiring electrocardiogram segments which are the same as the starting time and the ending time of the trend time period in all the electrocardiogram data, namely extracting the electrocardiogram segments which are the same time period as the trend time period, so that the marking of all the electrocardiogram segments can be realized at the same time. The trend time period is utilized to extract the electrocardiogram fragments of all electrocardiogram data, so that the electrocardiogram fragments corresponding to abnormal trends can be simultaneously marked, and the abnormal electrocardiogram fragments in the left atrium and the abnormal electrocardiogram fragments in the right atrium can be accurately extracted.
As shown in fig. 7, in one embodiment, the acquiring left atrial electrocardiogram data acquired through a left atrial lead and acquiring right atrial electrocardiogram data acquired through a right atrial lead includes:
and 702, acquiring positive and negative potentials of the left atrial lead in real time, and measuring and calculating to obtain the potential difference of the left atrial lead.
The positive electrode and the negative electrode of the left atrium lead are electrodes arranged at the left atrium part of the human body and comprise a positive electrode and a negative electrode; the potential difference refers to the difference between the positive electrode potential and the negative electrode potential. In one embodiment, the electrodes disposed in the left atrial region of the body may be electrodes of an esophageal catheter. Wherein, the positive pole can be the top electrode of the esophageal catheter, and the negative pole can be the side ring electrode of the esophageal catheter. The potential of the top electrode of the esophageal catheter and the potential of the side ring electrode of the esophageal catheter can be acquired in real time; and measuring and calculating the potential difference of the left atrial lead, namely measuring and calculating the potential difference between the potential of the top electrode of the esophageal catheter and the potential of the side ring electrode of the esophageal catheter, so as to obtain the potential difference of the left atrial lead.
And step 704, tracing and obtaining the left atrium electrocardiogram data according to the potential difference of the left atrium leads.
Wherein tracing refers to tracing a recording. The potential difference between the positive electrode potential and the negative electrode potential of the left atrial lead can reflect the potential relation between the positive electrode potential and the negative electrode potential of the left atrial lead, for example, when the potential difference is greater than zero, the positive electrode potential can be obtained to be higher than the negative electrode potential; when the potential difference is less than zero, the potential of the positive electrode is lower than that of the negative electrode; when the potential difference is equal to zero, the positive electrode potential is equal to the negative electrode potential; therefore, the left atrial electrocardiogram data can be drawn and recorded according to the potential difference of the left atrial lead. In one embodiment, the judgment can be made according to the calculated potential difference, that is, when the potential difference is greater than zero, the positive electrode potential is higher than the negative electrode potential, and an upward waveform can be traced; when the potential difference is less than zero, the potential of the negative electrode potential is higher than that of the positive electrode potential, and a downward waveform is traced. Therefore, the electrocardiogram data of the left atrium can be obtained by tracing according to the potential difference acquired in real time.
And step 706, acquiring the positive and negative electric potentials of the right atrial lead in real time, and measuring and calculating to obtain the potential difference of the right atrial lead.
Wherein, the positive and negative electrodes of the right atrium lead refer to electrodes arranged at the right atrium part of the human body, and comprise a positive electrode and a negative electrode; the potential difference refers to the difference between the positive electrode potential and the negative electrode potential. In one embodiment, the right atrial lead may be a right anterior chest bipolar lead. Wherein, the positive pole can be positioned between 4 ribs or xiphoid process on the right edge of the sternum, and the negative pole can be positioned between 2 ribs on the right edge of the sternum or the sternum. The positive electrode potential and the negative electrode potential in front of the right chest can be obtained in real time; and measuring the potential difference of the right atrial lead, namely measuring the potential difference between the electrode potential between 4 ribs on the right edge of the sternum and the electrode potential of the sternum peduncle, so as to obtain the potential difference of the right atrial lead.
And 708, obtaining right atrial electrocardiogram data by tracing according to the potential difference of the right atrial lead.
Wherein tracing refers to tracing a recording. The potential difference between the positive electrode potential and the negative electrode potential of the right atrial lead can reflect the potential relation between the positive electrode and the negative electrode of the right atrial lead, for example, when the potential difference is greater than zero, the positive electrode potential can be obtained to be higher than the negative electrode potential; when the potential difference is less than zero, the potential of the positive electrode is lower than that of the negative electrode; when the potential difference is equal to zero, the positive electrode potential is equal to the negative electrode potential; therefore, right atrial electrocardiogram data can be obtained by drawing and recording according to the potential difference of the right atrial lead. In one embodiment, the judgment can be made according to the calculated potential difference, that is, when the potential difference is greater than zero, the positive electrode potential is higher than the negative electrode potential, and an upward waveform can be traced; when the potential difference is less than zero, the potential of the negative electrode potential is higher than that of the positive electrode potential, and a downward waveform is traced. Therefore, right atrial electrocardiogram data can be obtained by tracing according to the potential difference acquired in real time.
As shown in fig. 8, in one embodiment, the left atrial electrocardiogram data includes: esophageal bipolar lead electrocardiographic data; the right atrial electrocardiogram data comprises a plurality of right chest bipolar lead electrocardiogram data. The esophagus bipolar lead electrocardiogram data refers to electrocardiogram data obtained by esophagus lead correspondence. Because the motor part of the esophagus leads is positioned in the esophagus behind the left atrium, the esophagus leads have very obvious expression advantages for the depolarization of the atrium, and particularly have important application value in the aspect of differential diagnosis of complicated and difficult electrocardiograms (such as separating and searching atrioventricular of wide QRS tachycardia), so that the esophagus bipolar lead electrocardiogram data can be used as the electrocardiogram data of the left atrium; the right chest bipolar lead electrocardiogram data is electrocardiogram data which is obtained by corresponding leads in the front of the right chest of a human body.
