s11, acquiring electrocardiosignals of a plurality of leads of the electrocardio monitoring equipment.
The plurality of leads are connected to the electrocardio monitoring equipment through the lead connection ports, and the electrocardio monitoring equipment monitors electrocardio signals of a human body in real time through the plurality of leads so as to acquire electrocardio signals acquired by the plurality of leads. The electrocardiosignals are electrocardio data which are acquired by a plurality of leads and are used for representing the electrocardio state of the human body.

S12, analyzing the electrocardiosignals and determining a preferred lead with the signal quality meeting preset conditions.
The preset condition is the condition that the electrocardiosignal quality is optimal, and the electrocardiosignal obtained by the electrocardiosignal monitoring equipment is preprocessed to remove noise interference, so that the electrocardiosignal removed by the noise interference is analyzed, a lead with optimal signal quality is determined, and the lead is determined to be a preferred lead.
S13, determining the preferred lead as the current calculation lead, and displaying at least one preferred lead.
After determining one or more leads with the best signal quality, the electrocardio monitoring equipment can take the preferred lead as a current calculation lead and collect electrocardio signals through the current calculation lead. The electrocardio monitoring equipment is provided with a display interface of electrocardio parameters, and when the electrocardio monitoring equipment determines the preferred leads, at least one preferred lead can be displayed in the display interface of the electrocardio monitoring equipment, so that the medical staff can conveniently confirm the current calculation lead.
Taking a preferred lead as an example, when the determined preferred lead is the II lead, the text "the current preferred lead is the II lead" is displayed on the display interface, or the II lead is prompted by a popup window as the preferred lead, or the II lead may be highlighted on the display interface, or may be displayed in other manners, which is not limited herein specifically.
According to the method for determining the electrocardiosignal calculation leads, the electrocardiosignals collected by the plurality of leads of the electrocardiosignal monitoring equipment are used for determining the preferable leads of which the electrocardiosignal quality meets the preset condition, the preferable leads are determined to be the current calculation leads and are displayed on the electrocardiosignal monitoring equipment, medical staff can conveniently determine the current calculation leads for monitoring the electrocardiosignals, so that the medical staff can monitor the electrocardiosignals by adopting the current calculation leads, the consistency of the current calculation leads used by the medical staff and the electrocardiosignal monitoring result is ensured, and meanwhile, the monitoring accuracy of electrocardiosignal parameters is improved.
In this embodiment, a method for determining an electrocardiographic calculation lead is provided, which may be used in medical devices such as electrocardiographic monitoring, and fig. 2 is a flowchart of a method for determining an electrocardiographic calculation lead according to an embodiment of the present application, as shown in fig. 2, where the flowchart includes the following steps:
s21, acquiring electrocardiosignals of a plurality of leads of the electrocardio monitoring equipment. The detailed description refers to the corresponding related descriptions of the above embodiments, and will not be repeated here.
S22, analyzing the electrocardiosignals and determining a preferred lead with the signal quality meeting preset conditions. The detailed description refers to the corresponding related descriptions of the above embodiments, and will not be repeated here.
S23, determining the preferred lead as the current calculation lead, and displaying at least one preferred lead.
The electrocardiographic monitoring device supports automatic switching and manual switching of the calculation leads, specifically, when the electrocardiographic monitoring device is in the automatic switching mode, the step S23 may include:
s231, when the initial calculated lead is not a preferred lead, determining at least one preferred lead as the current calculated lead and displaying the at least one preferred lead.
The initial calculation lead is a calculation lead when the medical staff starts the electrocardio monitoring equipment to use, and the calculation lead is used for analyzing the heart rhythm according to the electrocardio signals. The calculation lead can be set manually by a medical staff or can be used last time by the electrocardio monitoring equipment. Taking a 5-electrode system as an example, the initial calculation lead may select one or more of an I lead, II lead, III lead, AVR lead, AVL lead, AVF lead, V lead, as shown in FIG. 4. It should be noted that for a 3-electrode system, it makes the determination of the calculated leads, but does not make the lead preference.
The electrocardio monitoring equipment supports the setting of automatic switching mode, and medical personnel can select the automatic switching mode according to the demand. Taking the 5-electrode system shown in fig. 4 as an example, an automatic switching mode may be set in the setting box, and the healthcare worker may select an "automatic" option when setting, so as to compare the initial calculated lead with the preferred lead when determining the preferred lead, and determine whether the initial calculated lead is the preferred lead. If the initial calculated lead is not the preferred lead, the electrocardiographic monitoring device automatically takes the preferred lead as the current calculated lead while displaying the preferred lead information.
For example, if the preferred lead determined by the electrocardiograph monitoring device is a II lead, the electrocardiograph monitoring device automatically uses the II lead as the current calculation lead, and directly changes the initial calculation lead waveform displayed in the display interface into a waveform of the II lead, and the II lead collects electrocardiograph data for heart rate and arrhythmia analysis.
If the initial calculation lead is a preferable lead, the acquisition of the electrocardiographic signal may be continued by using the initial calculation lead.
Specifically, when the electrocardiographic monitoring device is in the manual switching mode, the step S23 may include:
s232, displaying prompt information of the preferred leads, wherein the prompt information is used for prompting a user to confirm the leads.
When the electrocardiograph monitoring equipment determines the preferred lead, the prompting information of the preferred lead is displayed on the display interface, and the prompting information can be a popup window prompting, a text prompting or a flashing prompting, is not limited in the form of prompting information, and can be determined according to actual needs by a person skilled in the art.
When the medical staff observes the preferred lead information prompted on the electrocardiographic monitoring device, the initial calculated lead currently used by the medical staff is compared with the preferred lead to confirm whether the calculated lead used by the medical staff is the preferred lead.
S233, replacing the initial calculation lead with the current calculation lead in response to the confirmation operation of the preferred lead.
If the initial computed lead is not the preferred lead, the healthcare worker can manually confirm the preferred lead and monitor the electrocardiographic data using the preferred lead as the current computed lead. Accordingly, the electrocardiographic monitoring device may respond to a confirmation operation of the preferred lead by the medical staff, by which the preferred lead is determined to be the current calculation lead for electrocardiographic monitoring, and the current calculation lead is used for replacing the initial calculation lead to monitor electrocardiographic parameters, namely, the current calculation lead is used for analyzing the heart rate and arrhythmia of the human body.
As an alternative embodiment, the step S23 may further include: when multiple leads are displayed simultaneously, at least one preferred lead is displayed overhead.
Multiple lead information can be displayed on a display interface of the electrocardiograph monitoring device at the same time, and the leads with better signal quality are set on top, namely one or more preferred leads are set on the lead information display area for top display. When a plurality of leads are displayed simultaneously, at least one preferred lead is arranged on the top for display, so that medical staff can know the lead with the better current electrocardiosignal.
Optionally, the at least one preferred lead determined above is the optimal lead. The optimal leads are leads with optimal signal quality, which are determined by analyzing the signal quality of each lead. At least one preferred lead is an optimal lead, so that the preferred lead for electrocardiosignal monitoring can be ensured to be the optimal lead, and the monitoring accuracy of the electrocardiosignal is further ensured.
According to the method for determining the electrocardio calculation leads, when the initial calculation leads exist and the initial calculation leads are not the preferred leads, at least one preferred lead is determined to be the current calculation lead, namely the preferred lead is used for replacing the initial calculation lead as the current calculation lead, so that medical staff can monitor the optimal electrocardio signals in real time, and accuracy of heart rate detection and arrhythmia analysis is improved. The determination of the calculation lead supports manual modification of the medical staff, and the modification of the calculation lead does not modify the setting of the medical staff, so that the consistency of the calculation lead confirmed by the medical staff and the electrocardiosignal monitoring result is ensured.
In this embodiment, a method for determining an electrocardiographic calculation lead is provided, which may be used in medical devices such as electrocardiographic monitoring, and fig. 3 is a flowchart of a method for determining an electrocardiographic calculation lead according to an embodiment of the present application, and as shown in fig. 3, the flowchart includes the following steps:
s31, acquiring electrocardiosignals of a plurality of leads of the electrocardio monitoring equipment. The detailed description refers to the corresponding related descriptions of the above embodiments, and will not be repeated here.
S32, analyzing the electrocardiosignals and determining a preferred lead with the signal quality meeting preset conditions.
Specifically, the step S32 may include:
s321, performing characteristic analysis on the electrocardiosignals to obtain time-frequency characteristic values corresponding to the electrocardiosignals.
And the electrocardio monitoring equipment performs data preprocessing, time domain feature calculation and frequency domain feature calculation on the electrocardiosignals acquired by each lead to obtain a time-frequency feature value corresponding to each electrocardiosignal. Specifically, the electrocardiograph monitoring device can input electrocardiograph signals acquired by the leads into a low-pass filter and a high-pass filter, so that noise interference is removed.
And the electrocardio monitoring equipment analyzes the electrocardio data after noise interference is removed, and calculates the corresponding time domain characteristics and frequency domain characteristics. Wherein the time domain features include, but are not limited to, extreme point number, peak amplitude and width information; the frequency domain features include, but are not limited to, QRS complex primary band energy and electrocardiographic signal band energy information.
S322, comparing the time-frequency characteristic values corresponding to the plurality of leads to obtain a comparison result of the time-frequency characteristic values.
And comparing the time-frequency characteristics corresponding to the leads obtained by calculation by the electrocardio monitoring equipment with a preset threshold value, determining the signal noise condition corresponding to each lead, and obtaining a comparison result of the time-frequency characteristic values. The preset threshold is a preset time-frequency characteristic value for determining the noise state, and can be determined according to actual needs, which is not limited herein.
S323, determining the lead with the optimal electrocardiosignal from the leads based on the comparison result of the time-frequency characteristic values, and determining the lead with the optimal electrocardiosignal as the preferred lead.
And the electrocardio monitoring equipment can determine the lead with the optimal electrocardio signal from a plurality of leads according to the comparison result of the time-frequency characteristic values, and takes the lead as the optimal lead. Meanwhile, the electrocardiograph monitoring device can generate prompt information of the preferred lead, and the prompt information can be popup window prompt, text prompt and the like, and is not particularly limited herein.
As an optional embodiment, the step S32 may further include:
(1) It is determined whether the number of preferred leads is equal to the target number.
The target number is the preset number of preferred leads corresponding to the current electrode system and analysis mode. The electrocardiograph monitoring device may count the number of preferred leads currently determined to determine whether the number of preferred leads is equal to the target number. And (3) outputting prompt information of the preferred leads when the number of the target leads is equal to the number of the targets, displaying the prompt information on a display interface of the electrocardiograph monitoring equipment, and otherwise, executing the step (2).
(2) When the number of preferred leads is not equal to the target number, the preferred leads continue to be determined from the remaining leads.
When the number of the preferred leads is not equal to the target number, the electrocardiograph monitoring device does not complete the determination of the preferred leads, at this time, the electrocardiograph monitoring device can continue to conduct lead preference from the rest leads so as to continuously determine other preferred leads from the leads until the number of the preferred leads is consistent with the target number.
The relation between the number of the determined preferred leads and the target number is detected to determine whether the preferred leads are determined completely, so that the determination of the preferred leads can be ensured to be more comprehensive, and the influence of omission on the electrocardiographic monitoring effect is avoided.
Optionally, the step of determining the number of targets may include:
(1) Setting information of the electrocardiographic monitoring device is obtained, wherein the setting information comprises an analysis mode.
The setting information is related information that medical personnel can set the electrocardiograph monitoring process of the electrocardiograph monitoring equipment through an upper computer corresponding to the electrocardiograph monitoring equipment, the setting information comprises the setting of an analysis mode, the setting of an electrode system and the like, and the default setting of the electrocardiograph monitoring equipment can be adopted.
When the medical staff adopts the electrocardio monitoring equipment to carry out the electrocardio monitoring of the human body, the electrocardio monitoring equipment can respond to the monitoring operation of the medical staff and acquire the setting information of the current electrocardio monitoring equipment so as to determine corresponding lead information according to the setting information.
For example, the electrocardiographic monitoring device may determine the number of initially available leads corresponding to the electrode system based on current electrode system information. At the same time, the selection and validation of the initial calculated leads can be determined from the electrode system information, e.g., under a 5-electrode system, the initial calculated leads can select one or more of the I, II, III, AVR, AVL, AVF, V leads.
The current calculation lead used for the electrocardio parameters is selected from the plurality of leads, so that the calculation lead is more beneficial to help medical staff judge the characteristics of the electrocardio signals, and the electrocardio parameters are convenient for the medical staff to acquire.
It should be noted that each lead supports a preferred mode, and that subsequent lead preference can be performed when the preferred mode of the lead is on.
(2) And determining the target number of the preferred leads based on the analysis mode in which the electrocardiograph monitoring device is currently located.
The analysis mode comprises a single-lead mode and a multi-lead mode, and the electrocardio monitoring equipment can determine the target number of the preferred leads corresponding to the analysis mode according to the analysis mode. The number of the selected preferred leads is represented by N, and when the analysis mode is a single lead mode, the target number of the preferred leads is 1; when the analysis mode is a multi-lead mode, the target number of preferred leads can be set according to actual requirements, where N is greater than or equal to 2.
