Detailed Description
For further illustration of the various embodiments, the invention is provided with the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments and together with the description, serve to explain the principles of the embodiments. With reference to these matters, one of ordinary skill in the art will understand other possible embodiments and advantages of the present invention.
The invention will now be further described with reference to the drawings and detailed description.
Embodiment one:
The embodiment of the invention provides a method for quickly identifying atrioventricular block, as shown in fig. 1, which is a flow chart of the method for quickly identifying atrioventricular block, and comprises the following steps:
S1: the P-wave position, Q-wave position and R-wave position are identified from the electrocardiographic data, and PR interval, PP interval and RR interval of each heart beat are calculated.
The PP interval is the time interval between two P waves in the current heart beat and the next heart beat, and the RR interval is the time interval between R waves in two QRS waves in the current heart beat and the next heart beat. PP intervals are typically used to calculate ventricular rate, RR intervals are typically used to calculate atrial rate, and both are normally identical.
The PR interval is the time interval from the start of the P wave to the start of the QRS wave, which varies with age, with the greater the age or the slower the heart rate, the longer the PR interval.
S2: judging whether a plurality of continuous heartbeats meet the following conditions: the PR interval for each heart beat is greater than the PR interval threshold, and if present, a primary atrioventricular block auxiliary identification map is constructed from the PR intervals.
The first-degree atrioventricular block is characterized by an extension of the atrioventricular conduction time, i.e., an RP interval greater than a PR interval threshold, and based on this principle, the method for constructing a graph for assisting in identifying a first-degree atrioventricular block is set in this embodiment as follows: and (3) representing PR intervals and PR interval thresholds of each heart beat in a plurality of continuous heart beats meeting the S2 condition by a transverse line segment representing the PR interval length, longitudinally arranging all PR interval representing line segments and PR interval threshold representing line segments according to the heart beat sequence in a head-end alignment mode, and distinguishing the part exceeding the PR interval threshold representing line segments from the part not exceeding the PR interval threshold representing line segments in the PR interval representing line segments by adopting different colors.
In this embodiment, for convenience of observation, the line segment representing the PR interval threshold is represented by a first color (green), the portion of the PR interval representing line segment that does not exceed the PR interval threshold is represented by a second color (blue), and the portion of the PR interval representing line segment that exceeds the PR interval threshold is represented by a third color (red), so that it can be clearly obtained whether the PR interval in the electrocardiographic data exceeds the PR interval threshold, as shown in fig. 2. Further, if the PR interval threshold is exceeded, the portion of the line segment that is indicated is not significantly available for highlighting in an equally magnified fashion.
The PR interval threshold is generally set to different values according to differences in ages, and is set to 210ms for adults in this embodiment.
S3: judging whether a plurality of continuous heartbeats meet the following two conditions, and if so, constructing a secondary I-type atrioventricular block auxiliary identification diagram according to PR intervals and RR intervals:
(1) The PR interval of the next heart beat is larger than the PR interval of the previous heart beat, and the time that the PR interval of the next heart beat exceeds the PR interval of the previous heart beat gradually decreases along with the increase of the heart beat sequence number;
(2) The RR interval of the next heart beat is smaller than the RR interval of the last heart beat, and the RR interval of the last heart beat is larger than the RR interval of other heart beats in a plurality of continuous heart beats.
The two conditions are characterized by a two degree type I atrioventricular block, namely, the PR interval is gradually prolonged and the prolonged part is gradually shortened, the RR interval of the last heart beat is prolonged to represent the shedding of the QRS wave, and a conduction period is formed from the PR interval to the shedding of the QRS wave.
Based on the characteristics of the second degree type i atrioventricular block, the method for constructing the second degree type i atrioventricular block auxiliary identification map in the embodiment is set as follows: PR intervals of each heart beat in the continuous plurality of heart beats meeting the S3 condition are represented by transverse line segments representing PR interval lengths, all PR interval representing line segments are longitudinally arranged according to the sequence of the heart beats in a head-end alignment mode, and the part exceeding the PR interval representing line segment of the last heart beat in the PR interval representing line segment of the next heart beat is distinguished from the part not exceeding the PR interval representing line segment of the last heart beat by adopting different colors; the RR interval of each heart beat in the continuous plurality of heart beats is represented by a transverse line segment representing the length of the RR interval, and all the RR interval representing line segments are longitudinally arranged according to the sequence of the heart beats in a head end alignment mode; the PR interval represents the alignment of the line segment with the PR interval represents the line segment with the heart beat.
For the sake of convenience of observation in this embodiment, a portion of the next cardiac PR interval that does not exceed the last cardiac PR interval is represented by a second color, a portion of the next cardiac PR interval that exceeds the last cardiac PR interval is represented by a third color, and an RR interval representation line segment is represented by the second color. As shown in fig. 3, it is apparent that the length of the line segment of the portion exceeding the last cardiac PR interval, which is represented by the third color, gradually decreases with an increase in cardiac cycle.
Further, the method further comprises taking a plurality of continuous heartbeats meeting the condition S3 as a conduction period, and making all the representation line segments corresponding to each conduction period pass through a rectangular frame; to distinguish between different conduction periods, the distinction is made by filling the rectangular box with different background colors for different conduction periods, as shown in fig. 3.
S4: judging whether a plurality of continuous heartbeats meet the following two conditions, if so, constructing a secondary II type or high atrioventricular block auxiliary identification diagram according to PR intervals and PP intervals:
(1) The PP intervals are the same for all heartbeats;
(2) The R-wave can be identified in the first heart beat, and the R-wave is not identified in one or more heart beats following the first heart beat.
The two conditions are characterized by two-degree II type or high atrioventricular block, namely the PR interval is constant, the P wave can not be seen only after the PR interval is not downloaded, the QRS wave can not be seen, and the PP interval is constant.
Based on the characteristics of the second degree ii or high atrioventricular block, the method for constructing the second degree ii or high atrioventricular block auxiliary identification chart in the embodiment comprises the following steps: p wave positions of each heart beat in the continuous plurality of heart beats meeting the S4 condition are represented by a plurality of transversely arranged vertical lines, and the distance between the connected vertical lines represents the PP interval length; and (3) representing the RP interval of the heart beat of the R wave by a transverse line segment representing the length of the PR interval, aligning the head end of the PR interval representing line segment with a vertical line corresponding to the heart beat, and connecting the connected vertical lines representing the PP interval, which are not corresponding to the heart beat of the R wave, by a line segment with different colors from the PR interval representing line segment.
In this embodiment, the PR interval is represented by a line segment in the second color, and the line segment connecting the connected vertical lines is represented by a third color, as shown in FIG. 4. As can be seen in fig. 4, when there is only one heart beat in which no R wave is identified, a second degree type ii atrioventricular block is indicated; when there are two heartbeats where no R wave is identified, a high (3:1) atrioventricular block is indicated; when there are three heartbeats where no R wave is identified, a high (4:1) atrioventricular block is indicated.
The PR interval representation line segment in the first heart beat PP interval indicates that the R wave can be identified in the heart beat, and the R wave is not identified in the subsequent heart beat, which indicates that the QRS wave is shed.
S5: judging whether a plurality of continuous heartbeats meet the following conditions: the PP intervals of all heartbeats are the same, the RR intervals of all heartbeats are the same, and the PP intervals are smaller than the RR intervals; if present, a three-degree atrioventricular block assistance identification map is constructed from the PP interval and the RR interval.
The three-degree atrioventricular block is characterized by no correlation between the P wave and the QRS wave, each maintaining its own rhythm, i.e., PP interval and RR interval, and by a very high Yu Xinshi rate, i.e., PP interval less than RR interval.
Based on the characteristics of the three-degree atrioventricular block, the construction method for setting the three-degree atrioventricular block auxiliary identification graph in the embodiment comprises the following steps: the P wave positions of each heart beat in the continuous plurality of heart beats meeting the S5 condition are represented by a plurality of transversely arranged vertical lines, and the length of marked lines for connecting the P wave positions to represent the vertical lines is used for representing the PP interval length; simultaneously, the R wave positions of each heart beat in the continuous plurality of heart beats are represented by a plurality of transversely arranged vertical lines, and the length of a marked line connecting the R wave positions to the vertical lines is used for representing the RR interval length; the PP interval indicates that the reticle is longitudinally aligned with the RR interval indicates that the reticle is head-end aligned.
The PP interval representation reticle and RR interval representation reticle in this embodiment are represented by different colors, as shown in fig. 5.
S6: the atrioventricular block identification is performed by means of the constructed auxiliary identification map of all atrioventricular blocks.
By the method of the embodiment, the heart beat characteristics are characterized through the visualized auxiliary identification graphic, and the constructed different types of auxiliary identification graphic can help doctors to quickly identify atrioventricular block.
