一种心电图分析方法、分析装置以及存储介质An electrocardiogram analysis method, analysis device and storage medium

技术领域technical field

本申请涉及心电图分析技术领域，特别是一种心电图分析方法、分析装置以及存储介质。The present application relates to the technical field of electrocardiogram analysis, in particular to an electrocardiogram analysis method, an analysis device and a storage medium.

背景技术Background technique

心电图(ECG)是利用心电图机从体表记录心脏每一心动周期所产生的电活动变化图形的技术。随着对健康的追求以及科技的不断发展，动态心电图检查，作为一种在患者日常生活中连续记录24小时或更长时间的心电活动的检查，并辅助计算机进行分析处理的新技术，越来越受到欢迎。较之普通心电图，动态心电图在24小时内可连续记录多达10万次左右的心动周期，这样，可以发现常规体表心电检查不易发现的心律失常和心肌缺血等，能够提高对非持续性心律失常，尤其是对一过性心律失常及短暂的心肌缺血发作的检出率，很好地扩大了心电图临床运用的范围。An electrocardiogram (ECG) is a technique that uses an electrocardiograph to record from the surface of the body the pattern of changes in electrical activity produced by the heart during each cardiac cycle. With the pursuit of health and the continuous development of science and technology, dynamic electrocardiography, as a new technology that continuously records the cardiac electrical activity of patients for 24 hours or more in daily life, and assists the computer for analysis and processing, has become more and more increasingly popular. Compared with ordinary ECG, Holter monitor can record up to 100,000 cardiac cycles continuously in 24 hours. In this way, arrhythmia and myocardial ischemia that are not easily detected by routine surface ECG can be found, which can improve the diagnosis and treatment of non-sustained ECG. The detection rate of arrhythmia, especially transient arrhythmia and transient myocardial ischemic attack, has greatly expanded the scope of clinical application of ECG.

由于动态心电图是受试者在日常生活中采集的信号，加之动态心电图采样设备的采样率相对较低，因此采集到的信号中，p波较不明显，这导致操作者在进行动态心电图分析的时候，无法简单快速的识别出病例的节律是否紊乱、传导是否正常。Since the Holter is the signal collected by the subjects in daily life, and the sampling rate of the Holter sampling equipment is relatively low, the P wave is less obvious in the collected signal, which leads the operator to perform Holter analysis. At this time, it is impossible to easily and quickly identify whether the rhythm of the case is disordered and whether the conduction is normal.

参阅图1，图1是本申请提供的心电图分析方法第一实施例的流程示意图，该方法包括：Referring to FIG. 1, FIG. 1 is a schematic flowchart of the first embodiment of the electrocardiogram analysis method provided by the present application, and the method includes:

步骤11：获取心电图中心动周期的P波参数。Step 11: Obtain the P wave parameters of the cardiac cycle in the electrocardiogram.

如图2所示，图2是心电图中一个心动周期的示意图。其中，心电图的横坐标表示时间，心电图的纵坐标表示检测信号值(如电压值)(图2中未示出横纵坐标)。其中，心电图包括多个心动周期，每个心动周期表示一个心拍，图2示出了一个心动周期。具体地，一个心动周期主要包括PR间期和QT间期，QT间期又包括QRS间期和JT间期。As shown in FIG. 2, FIG. 2 is a schematic diagram of one cardiac cycle in an electrocardiogram. The abscissa of the electrocardiogram represents time, and the ordinate of the electrocardiogram represents a detected signal value (eg, a voltage value) (the abscissa and ordinate are not shown in FIG. 2 ). Wherein, the electrocardiogram includes a plurality of cardiac cycles, each cardiac cycle represents a cardiac beat, and FIG. 2 shows a cardiac cycle. Specifically, a cardiac cycle mainly includes the PR interval and the QT interval, and the QT interval includes the QRS interval and the JT interval.

可以理解地，心电图可以包括一段时间多个心动周期，在本实施例中，可以获取该一段时间的所有心动周期的P波参数，也可以获取该一段时间内部分心动周期的P波参数，其中，该部分心动周期应该是连续的。例如，在一实施例中，心电图包含24小时的心动周期，则可以获取其中全部24小时的心动周期的P波参数，以便后续的处理操作，也可以获取其中连续的12小时的心动周期的P波参数，以便后续的处理操作。It can be understood that the electrocardiogram may include a period of time and multiple cardiac cycles. In this embodiment, the P wave parameters of all cardiac cycles in the period of time can be acquired, and the P wave parameters of some cardiac cycles in the period of time can also be acquired, wherein , this part of the cardiac cycle should be continuous. For example, in one embodiment, the electrocardiogram includes a 24-hour cardiac cycle, and the P wave parameters of the entire 24-hour cardiac cycle may be obtained for subsequent processing operations, and the P wave parameters of the continuous 12-hour cardiac cycle may also be obtained. Wave parameters for subsequent processing operations.

P波是心房除极波，代表左右二心房的激动。由于窦房结位于右心房内膜下，所以激动首先传到右心房，较晚传到左心房。右心房的除极作用因此也比左心房略早完毕。临床上为了实用起见，P波的前部代表右心房的激动，后部代表左心房的激动。分析P波对心律失常的诊断与鉴别诊断具有重要意义。The P wave is the atrial depolarization wave, which represents the excitation of the left and right atria. Since the sinoatrial node is located under the right atrium, the excitation is first transmitted to the right atrium and later to the left atrium. The depolarization of the right atrium is therefore also completed slightly earlier than that of the left atrium. In clinical practice, the front part of the P wave represents the activation of the right atrium, and the rear part represents the activation of the left atrium. Analysis of P wave is of great significance for the diagnosis and differential diagnosis of arrhythmia.

其中，P波参数包括：P波时限、P波形态、P波幅值、P波与QRS波关系、P波下传情况中的至少一个，另外，P波参数还可以包括PR间期、RP间期、PP间期、PP间期差等。The P wave parameters include: at least one of the P wave duration, the P wave shape, the P wave amplitude, the relationship between the P wave and the QRS wave, and the P wave downlink situation. In addition, the P wave parameters may also include PR interval, RP interval, PP interval, PP interval difference, etc.

P波时限是指P波的起始时间和终止时间之间的时间段，P波幅值包括P波端的最大信号值、最小信号值或最大信号值与最小信号值的差值，P波与QRS波关系是指P波数量和QRS波数量的比例关系，P波下传情况是指P波后面是否有紧跟的QRS波。The P wave time limit refers to the time period between the start time and the end time of the P wave, and the P wave amplitude includes the maximum signal value, the minimum signal value, or the difference between the maximum signal value and the minimum signal value at the P wave end. The relationship between QRS complexes refers to the proportional relationship between the number of P waves and the number of QRS complexes, and the case of P wave downlink refers to whether there is a QRS complex following the P wave.

进一步，根据上述P波参数还可以确定P波形态，P波形态可以根据不同的分类方式进行分类，例如可以将P波分为直立P波、倒置P波、正负双向P波和负正双向P波。Further, according to the above P wave parameters, the shape of the P wave can also be determined, and the shape of the P wave can be classified according to different classification methods. P waves.

步骤12：根据P波参数，确定心动周期的P波类型。Step 12: Determine the P wave type of the cardiac cycle according to the P wave parameters.

可选地，在一实施例中，可以根据P波类型建立多个P波模板。Optionally, in an embodiment, multiple P-wave templates may be established according to P-wave types.

具体地，每一P波模板对应一个P波类型，每一P波模板根据P波参数，对相应P波类型的心动周期进行统计。Specifically, each P wave template corresponds to one P wave type, and each P wave template counts the cardiac cycle of the corresponding P wave type according to the P wave parameters.

例如，P波模板包括模板A、模板B和模板C，在对一个心动周期进行分类时，确定该心动周期的P波类型，然后归类到一个P波模板中，如与模板A的类型相同，则将该心动周期归类到模板A，模板A对该心动周期进行计数统计。For example, the P wave template includes template A, template B, and template C. When classifying a cardiac cycle, the P wave type of the cardiac cycle is determined, and then classified into a P wave template, such as the same type as template A. , the cardiac cycle is classified into template A, and template A counts the cardiac cycle.

具体地，每一个P波模板都对应至少一个参数阈值，参数阈值跟P波模板对应的P波类型相关，例如，该P波模板对应的P波类型为P波下传，那么该参数阈值主要用于检测P波后面是否有紧跟的QRS波。因此，每一P波模板判断目标心动周期的P波参数是否满足对应的参数阈值；若满足，则对目标心动周期进行统计。Specifically, each P wave template corresponds to at least one parameter threshold, and the parameter threshold is related to the P wave type corresponding to the P wave template. For example, if the P wave type corresponding to the P wave template is P wave downlink, then the parameter threshold is mainly It is used to detect whether there is a QRS wave following the P wave. Therefore, each P wave template determines whether the P wave parameters of the target cardiac cycle meet the corresponding parameter threshold; if so, the target cardiac cycle is counted.

在一实施例中，可以对P波按照一种规则进行分类。例如，可以根据P波的前后波形来进行分类，具体地，可以检测P波后是否有紧跟的QRS波进行分类。In one embodiment, P waves may be classified according to a rule. For example, the classification can be performed according to the waveforms before and after the P wave, and specifically, whether there is a QRS wave following the P wave can be detected for classification.

进一步，基于上述规则，P波类型包括PR和单R，PR表示P波带有QRS波，单R表示R波前无，PR包括下传PR和未下传PR。Further, based on the above rules, the types of P waves include PR and single R. PR indicates that the P wave has a QRS complex, and single R indicates that there is no front of the R wave. PR includes downlink PR and non-downlink PR.

在另一实施例中，可以对P波按照至少两个规则进行分类。例如，根据P波参数确定不同维度的至少第一分类规则和第二分类规则；确定心动周期在第一分类规则下的第一P波类型，以及在第二分类规则下的第二P波类型。In another embodiment, P waves can be classified according to at least two rules. For example, at least a first classification rule and a second classification rule in different dimensions are determined according to the P wave parameters; the first P wave type of the cardiac cycle under the first classification rule and the second P wave type under the second classification rule are determined .

进一步，第一分类规则基于P波是否下传进行分类，第二分类规则基于P波形态进行分类。Further, the first classification rule performs classification based on whether the P wave is down-streamed, and the second classification rule performs classification based on the P wave shape.

具体地，基于第一分类规则，P波类型包括PR和单R，PR表示P波带有QRS波，单R表示R波前无，PR包括下传PR和未下传PR；基于第二分类规则，P波类型包括直立P波、倒置P波、正负双向P波和负正双向P波。Specifically, based on the first classification rule, the types of P waves include PR and single R, PR indicates that the P wave has a QRS complex, single R indicates that there is no front of the R wave, and PR includes downlink PR and non-downlink PR; based on the second classification As a rule, the types of P waves include upright P waves, inverted P waves, positive and negative bidirectional P waves, and negative positive bidirectional P waves.

其中，正常P波在Ⅰ、Ⅱ、aVF，V4～V6导联直立，aVR导联倒置，其波顶一般是圆凸的，偶有轻度切迹或双峰。在肢体导联中，其高度不超过0.25mV；在胸导联中，直立P波高度则不超过0.2mV。正常P波的宽度不超过0.11秒。Among them, the normal P wave is upright in leads I, II, aVF, V4-V6, and inverted in lead aVR. In the limb leads, its height does not exceed 0.25 mV; in the chest leads, the upright P wave height does not exceed 0.2 mV. A normal P wave is no more than 0.11 seconds wide.

当p波在Ⅱ、Ⅲ、aVF导联倒置，而aVR直立时，则称为逆行性p波，表示激动起源于房室交界。When the p wave is inverted in leads II, III, and aVF and the aVR is upright, it is called a retrograde p wave, indicating that the excitation originates from the atrioventricular junction.

正负双向P波是指P波开始阶段直立，而结束阶段倒置；负正双向P波是指P波开始阶段倒置，而结束阶段直立。A positive and negative bidirectional P wave means that the initial phase of the P wave is upright and the end phase is inverted;

可以理解地，由于采用了多个维度的分类方式，因此，同一个心动周期在每一个分类方式中都可以确定一个类型，即不同类型的P波中可能有相同的心动周期。It is understandable that, since the classification methods of multiple dimensions are adopted, one type of cardiac cycle can be determined in each classification method, that is, different types of P waves may have the same cardiac cycle.

步骤13：根据心动周期的P波类型，将心电图的心动周期归类至对应的P波模板中。Step 13: According to the P wave type of the cardiac cycle, classify the cardiac cycle of the electrocardiogram into the corresponding P wave template.

模板是同一P波类型的心动周期的集合。可以理解地，这里的模板类似于一个文件夹，步骤13用于将所有的心动周期分类至各个对应的P波模板中。A template is a collection of cardiac cycles of the same P wave type. Understandably, the template here is similar to a folder, and step 13 is used to classify all cardiac cycles into corresponding P wave templates.

If the quantity is 6570, the number "6570" will be displayed in the lower right corner of the "R" template logo.

进一步，在一实施例中，还可以采用至少两种不同分类维度对心动周期进行分类。具体地，根据P波参数和预设第一分类规则，确定心动周期的母P波类型，以及根据P波参数和预设第二分类规则，确定每一母P波类型中的心动周期的子P波类型；其中，预设第一分类规则和预设第二分类规则的分类维度不同。Further, in one embodiment, at least two different classification dimensions can also be used to classify the cardiac cycle. Specifically, the parent P wave type of the cardiac cycle is determined according to the P wave parameter and the preset first classification rule, and the child of the cardiac cycle in each parent P wave type is determined according to the P wave parameter and the preset second classification rule P wave type; wherein, the classification dimensions of the preset first classification rule and the preset second classification rule are different.

其中，P波模板包括至少一母P波模板和每一母P波模板包含的至少一子P波模板。The P wave template includes at least one parent P wave template and at least one sub P wave template included in each parent P wave template.

进一步，如图3b所示，显示至少一母模板标识，每一母模板标识对应一个母P波模板；在获取到基于目标母模板标识的点击指令时，显示目标母模板标识对应的至少一子模板标识；在获取到基于目标子模板标识的点击指令时，显示目标子模板标识对应的心动周期。Further, as shown in Figure 3b, at least one parent template identification is displayed, and each parent template identification corresponds to a parent P-wave template; when the click instruction based on the target parent template identification is obtained, at least one child corresponding to the target parent template identification is displayed.

When the template is identified, the cardiac cycle in the "upright" sub-P wave template in the corresponding "PR" parent P wave template is displayed in the right area.

In the floating window, detailed parameters corresponding to the cardiac cycle can also be displayed in the setting area. In addition, operations such as zooming, dragging, etc. can also be performed on the new map segment displayed in the suspension. Taking zooming as an example, the mouse wheel can be used to zoom, or the boundary of the floating window can be dragged to zoom. Further, when a preset operation instruction for the floating window (such as double-click or right-click drop-down menu selection) is obtained again, the cardiac cycle is restored, and the floating window disappears.

在另一实施例中，还可以将多个心动周期重叠显示，具体地，将目标P波类型对应的至少部分心动周期进行叠加；显示叠加后的至少部分心动周期。其中，关心心电图叠加显示的效果可以参阅后面的实施例，这里不再详述。In another embodiment, multiple cardiac cycles may also be displayed in an overlapping manner, specifically, at least part of the cardiac cycles corresponding to the target P wave type are superimposed; and at least part of the cardiac cycles after the superimposition is displayed.

参阅图4，图4是本申请提供的心电图分析方法第二实施例的流程示意图，该方法包括：Referring to FIG. 4, FIG. 4 is a schematic flowchart of the second embodiment of the electrocardiogram analysis method provided by the present application, and the method includes:

步骤41：获取心电图中心动周期的P波参数。Step 41: Obtain the P wave parameters of the cardiac cycle in the electrocardiogram.

本步骤与上述步骤11类似，这里不再赘述。This step is similar to the above-mentionedstep 11, and will not be repeated here.

The difference is the abscissa, and a scatter plot of the PP interval difference is drawn.

可选地，由于散点图中的每一个点对应一个心动周期，因此，可以根据心动周期的不同类型，对散点图中的每一个点进行不同显示效果的表示。例如，在目标间期散点图中散点，根据其对应的心动周期中P波下传状态，显示不同的颜色。具体地，如果一个心动周期的P波下传，那么该心动周期对应的散点可以采用第一颜色表示，如果一个心动周期中的P波未下传，那么该心动周期对应的散点可以采用第二颜色表示。Optionally, since each point in the scatter diagram corresponds to one cardiac cycle, each point in the scatter diagram can be represented with different display effects according to different types of cardiac cycles. For example, in the target interval scatterplot, the scatter points are displayed in different colors according to their corresponding P-wave downgoing states in the cardiac cycle. Specifically, if the P wave of a cardiac cycle is transmitted down, the scatter point corresponding to the cardiac cycle can be represented by the first color; if the P wave in a cardiac cycle is not transmitted down, the scatter point corresponding to the cardiac cycle can be represented by the first color. The second color indicates.

以直方图为例：Take the histogram as an example:

当然，上述的几种散点图和直方图仅仅是为了举例，在其他实施例中，还可以包括PP间期、RR间期、PR间期和RP间期分别对应的散点图和直方图，这里不再一一举例。Of course, the above-mentioned scatter plots and histograms are only for examples, and in other embodiments, scatter plots and histograms corresponding to the PP interval, RR interval, PR interval, and RP interval, respectively, may also be included. , no more examples here.

对于散点图，一个散点表示一个心动周期，因此，可以通过对散点图中的点进行选择，以显示对应的心动周期。具体地，在获取到基于目标间期散点图中一个散点或指定区域的多个散点的选择指令时，显示被选择的散点对应的心动周期。For a scatter plot, one scatter point represents one cardiac cycle, so the corresponding cardiac cycle can be displayed by selecting points in the scatter plot. Specifically, when a selection instruction based on one scatter point or multiple scatter points in a designated area in the target interval scatter point diagram is obtained, the cardiac cycle corresponding to the selected scatter point is displayed.

对于选择一个区域内的多个散点，对应的多个心动周期，可以按照时序依次显示，例如，可以将显示屏幕划分为多个区域，每个区域显示一个心动周期。进一步，可以从显示的多个心动周期中选择，然后单独显示选择的心动周期，如果选择的心动周期数量为2，可以将两个心动周期对应显示。For selecting multiple scattered points in one area, the corresponding multiple cardiac cycles can be displayed in sequence according to the time sequence. For example, the display screen can be divided into multiple areas, and each area displays one cardiac cycle. Further, it can be selected from the displayed multiple cardiac cycles, and then the selected cardiac cycles can be displayed individually. If the number of selected cardiac cycles is 2, two cardiac cycles can be displayed correspondingly.

在另一实施例中，还可以将多个心动周期重叠显示，具体地，将目标P波类型对应的至少部分心动周期进行叠加；显示叠加后的至少部分心动周期。In another embodiment, multiple cardiac cycles may also be displayed in an overlapping manner, specifically, at least part of the cardiac cycles corresponding to the target P wave type are superimposed; and at least part of the cardiac cycles after the superimposition is displayed.

对于直方图，一个条柱表示具有一定范围间期的多个心动周期，因此，可以通过对条柱进行选择，以显示对应的多个心动周期。具体地，在获取到基于目标间期直方图中至少一个条柱的选择指令时，显示被选择的条柱对应的心动周期。For the histogram, a bar represents a plurality of cardiac cycles with a certain range of intervals, so the bars can be selected to display the corresponding cardiac cycles. Specifically, when a selection instruction based on at least one bar in the target interval histogram is acquired, the cardiac cycle corresponding to the selected bar is displayed.

另外，还可以对多个条柱同时进行选择，多个条柱对应的多个心动周期也可以按照时序依次显示，例如，可以将显示屏幕划分为多个区域，每个区域显示一个心动周期。进一步，可以从显示的多个心动周期中选择，然后单独显示选择的心动周期，如果选择的心动周期数量为2，可以将两个心动周期对应显示。In addition, multiple bars can be selected at the same time, and multiple cardiac cycles corresponding to the multiple bars can also be displayed sequentially in time sequence. For example, the display screen can be divided into multiple areas, and each area displays one cardiac cycle. Further, it can be selected from the displayed multiple cardiac cycles, and then the selected cardiac cycles can be displayed individually. If the number of selected cardiac cycles is 2, two cardiac cycles can be displayed correspondingly.

在另一实施例中，还可以将多个心动周期重叠显示，具体地，将目标P波类型对应的至少部分心动周期进行叠加；显示叠加后的至少部分心动周期。In another embodiment, multiple cardiac cycles may also be displayed in an overlapping manner, specifically, at least part of the cardiac cycles corresponding to the target P wave type are superimposed; and at least part of the cardiac cycles after the superimposition is displayed.

对于重叠心动周期，如图7所示，图7是重叠心动周期示意图，在一实施例中，可以获取基于叠加心动周期中指定区域的插入指令；在指定区域插入P波；对插入P波之后的目标间期散点图或目标间期直方图进行更新。For overlapping cardiac cycles, as shown in FIG. 7 , which is a schematic diagram of overlapping cardiac cycles, in one embodiment, an insertion instruction based on a designated area in the overlapping cardiac cycle can be obtained; P waves are inserted in the designated areas; The target interval scatterplot or target interval histogram is updated.

另外，在获取到基于统计图中的至少一个目标统计元素的P波重检测指令时，根据选择的导联对至少一个目标统计元素对应的P波进行重新检测，并对统计图进行更新。以直方图为例，参阅图5，直方图支持选中区域进行右键操作，右键支持“P波重检测”功能，选中后可以弹出子菜单，支持选择某个导联作为重分析导联，点击后，系统会根据选中的分析导联重新检测选中区域心拍范围内的P波，检测完成后，会自动更新直方图。In addition, when a P wave re-detection instruction based on at least one target statistical element in the statistical chart is obtained, the P wave corresponding to the at least one target statistical element is re-detected according to the selected lead, and the statistical chart is updated. Taking the histogram as an example, see Figure 5. The histogram supports the right-click operation of the selected area. The right-click supports the "P wave re-detection" function. After selecting, a submenu will pop up, and a certain lead can be selected as the reanalysis lead. After clicking , the system will re-detect the P wave within the cardiac beat range of the selected area according to the selected analysis lead. After the detection is completed, the histogram will be automatically updated.

区别于现有技术，本实施例提供的心电图分析方法包括：获取心电图中心动周期的P波参数；根据P波参数建立统计图，以使心动周期根据对应的P波参数以一统计元素在统计图中表示。通过上述方式，通过对P波参数进行分析，在P波不明显的情况完成，完成对P波统计图显示，由于统计图显示直观，可以便捷的从统计图中获取到P波特征，避免了从心电图中不易获取特征的问题。进一步减少了分析时间，极大地提高了心电图分析效率。Different from the prior art, the electrocardiogram analysis method provided in this embodiment includes: acquiring P wave parameters of the cardiac cycle in the electrocardiogram; establishing a statistical map according to the P wave parameters, so that the cardiac cycle can be counted with a statistical element according to the corresponding P wave parameters. shown in the figure.

Since the statistical chart is intuitively displayed, the P wave characteristics can be easily obtained from the statistical chart, avoiding the need for The problem of not easily obtaining features from the ECG. The analysis time is further reduced and the efficiency of ECG analysis is greatly improved.
