Background

The target object may generally refer to various entities, such as a device, a human body, and the like.

In the related art, a plurality of acquisition parts of an abnormal part are acquired by a plurality of acquisition components to obtain a one-dimensional waveform signal corresponding to each acquisition part, and the one-dimensional waveform signal corresponding to each acquisition part is drawn into an image to obtain a target image.

In the embodiment of the present application, since the heart has a three-dimensional structure, the electrocardiographic signals are the representation of the electrical signals generated during the contraction and relaxation of the myocardium on the body surface, and are respectively around the body surface, the 12-lead electrocardiogram based on the wilson lead system represents the electrocardiographic changes on the front surface of the human body, each lead signal represents the secondary projection of the three-dimensional electrocardiographic signals of the heart on the acquisition part, and the projection diagram of the three-dimensional electrocardiographic signals of the heart is shown in fig. 8. Because the heart stereo electrocardiosignals are weak generally, a plurality of lead signals obtained by secondary projection have different losses, namely, the signals on each lead signal are lost, and the electrocardio image can reflect the abnormal condition of the heart inaccurately. In the embodiment of the present application, by selecting three orthogonal lead signals from the 12 lead signals, the three lead signals can represent signal distributions on axes in different directions, so that the three orthogonal lead signals can represent three-dimensional reflection of the electrical signals of the heart, and the three orthogonal lead signals have good comprehensiveness and high accuracy.

Step 303: the computer device obtains a signal value for each of the orthogonal signals at each sampling instant.

Each orthogonal signal is a signal in a time domain, the abscissa of each orthogonal signal is a sampling time, and the ordinate is a signal value.

In some embodiments, the first image is a 12-lead electrocardiogram, and the signal value at each sampling time in the orthogonal signals is the signal value of the voltage corresponding to the sampling time.

Step 304: the computer device sums the squares of the signal values of each of the orthogonal signals for each sampling instant to obtain a sum of the squares of the plurality of orthogonal signals, and squares the sum of the squares to obtain a vector value for the sampling instant.

In the embodiment of the application, the vector value of the equivalent vector signal at each sampling moment is obtained by squaring and re-evolution based on the signal values of the plurality of orthogonal signals, so that the vector value of the equivalent vector signal at each sampling moment obtained based on the vector values in the subsequent process represents the comprehensive signal value in the three-dimensional direction, the equivalent vector signal can represent the comprehensive change trend of the waveform signal in the three-dimensional direction, the fusion effect is improved, the representativeness of the equivalent vector signal is better, the abnormal condition of the abnormal part is reflected on the basis of a second image formed by the equivalent vector signal in the subsequent process, and the accuracy of the reflected abnormal condition can be improved.

In one implementation, the computer device respectively equates the axes corresponding to the three orthogonal signals to an X-axis, a Y-axis, and a Z-axis to form an equivalent three-dimensional lead coupling. Continuing with the example that the first image is a 12-lead electrocardiogram, the three orthogonal signals are respectively chest V2 lead signal, compression lower limb lead signal AVF and chest V6 lead signal, and the axes corresponding to chest V2 lead signal, compression lower limb lead signal AVF and chest V6 lead signal are respectively equivalent to X axis, Y axis and Z axis to form an equivalent three-dimensional lead coupling axis, so that the vector value of the equivalent vector signal at each sampling time can be obtained by the following equivalent formula.

The equivalent formula:

wherein, for each sampling instant, V6 represents the signal value of the thoracic V6 lead signal at that instant; v2 represents the signal value of thoracic V2 lead signal at that time; AVF represents the signal value of the pressurized lower limb lead signal AVF at the moment; m represents a signal value of the equivalent vector signal at the time, and an absolute value of the signal value is taken as a vector value.

Step 305: the computer device generates an equivalent vector signal based on each sample time and the vector value for each sample time.

The computer device draws an image by taking each sampling moment as a numerical value of an abscissa and taking a vector value of each sampling moment as a numerical value of an ordinate, and obtains an equivalent vector signal taking the sampling moment as the abscissa and the vector value as the ordinate.

In some embodiments, the first image is a 12-lead electrocardiogram; it should be noted that, because the vector value of the equivalent vector signal in this embodiment at any time is a positive value, that is, the wilson center end of the wilson system is equivalent to the zero point of the voltage value, and all QRS waves representing ventricular contraction are converted into positive waves, such conversion is not only beneficial to analyzing lead signals, but also beneficial to automatic analysis of current computer equipment, so that the calculation amount of waveform analysis is greatly reduced, and further, when the method provided by this embodiment of the present application is applied to a wearable miniaturized electrocardiographic analysis system, the calculation efficiency and application efficiency of the wearable miniaturized electrocardiographic analysis system will be improved.

Step 306: the computer device generates a second image based on the plurality of waveform signals and the equivalent vector signal.

Wherein the second image is used for reflecting the abnormal condition of the abnormal part. In one implementation, the computer device adds an equivalent vector signal to the first image, resulting in a second image. In this way, the second image includes the equivalent vector signal and the plurality of waveform signals at the same time, and the abnormal condition of the abnormal portion is reflected in common based on the plurality of waveform signals and the equivalent vector signal, so that the accuracy of the reflected abnormal condition of the abnormal portion can be improved.

In some embodiments, the first image is a 12-lead electrocardiogram, and the equivalent vector signal is added to the 12-lead electrocardiogram to obtain a second image, which is an image including 13 waveform signals.

In one implementation, the 12 lead signals and the equivalent vector signals are displayed on the same interface; for example, referring to fig. 9, fig. 9 is a schematic diagram of a 13-lead electrocardiogram consisting of 12 lead signals and equivalent vector signals, which are arranged at the bottom of the 12 lead signals as auxiliary lead signals for auxiliary analysis of the 12 lead signals. For example, if a signal of a target ii lead signal in the 12 lead signals at a certain sampling time is missing, the vector value corresponding to the sampling time in the equivalent vector signal may be assigned to the target ii lead signal to compensate for the missing of the signal on the target ii lead signal. In another implementation, the abnormal condition of the heart is reflected directly based on waveform characteristics of a plurality of waveforms in the equivalent vector signal.

Step 307: the computer device determines the operation condition of the abnormal part based on the second image.

Wherein each waveform signal comprises a plurality of waveforms; in this embodiment, the computer device determines start and end points of a plurality of waveforms in each waveform signal based on the equivalent vector signal; the computer device determining a waveform characteristic of each waveform based on the start and end points of the plurality of waveforms; the computer device determines an operation condition of the abnormal portion based on waveform features in the plurality of waveform signals.

In some embodiments, the first image is a 12-lead electrocardiogram, each waveform signal is a lead signal, the abscissa of the lead signal represents the sampling time, and the ordinate represents the voltage signal value. The multiple waveforms included in each lead signal are respectively a P wave, a QRS wave and a T wave; wherein, P wave is depolarization wave of atrium, QRS wave is depolarization wave of ventricle, and T wave is repolarization wave of ventricle. It should be noted that the start and end points of each waveform are used to determine the duration of each waveform, and after the duration of each waveform is determined, the lead signal can be segmented to obtain a plurality of waveforms, and the shape and duration of each waveform within its duration can represent the waveform characteristics of the waveform. For example, the duration of the P-wave is generally no more than 0.11 seconds, and the voltage amplitude is no more than 0.25 millivolts; if the duration of the P-wave exceeds 0.11 seconds, or the voltage amplitude exceeds 0.25 milliseconds, then an abnormal condition in the operation of the atrium is determined.

It should be noted that, because a plurality of lead signals obtained by the cardiac stereo electrocardiographic signal through the secondary projection all have different losses, and because different losses occur when the electrocardiographic signal changes caused by some cardiac diseases are projected on each lead signal, the start point and the end point of each waveform are difficult to position, so that when a doctor uses an electrocardiographic image, the doctor needs to combine a plurality of lead signals according to experience to determine the characteristic change of each electrocardiographic signal, and the complexity and difficulty of the doctor analyzing the cardiac diseases based on the electrocardiographic image are increased, thereby reducing the efficiency of reflecting the abnormal conditions of the heart based on the electrocardiographic image. In the embodiment of the application, the one-dimensional electrocardiosignals are inverted into the space electrocardio vector signals by using a three-dimensional equivalent coordinate system, so that when the abnormal condition of the heart is reflected and the running condition is determined based on a new electrocardio image consisting of a plurality of lead signals and equivalent vector signals, the abnormal condition of the heart can be analyzed in an auxiliary manner based on the equivalent vector signals; for example, the start and end points of a plurality of lead signals can be determined based on equivalent vector signals; therefore, the efficiency of reflecting the abnormal condition of the heart based on the electrocardio image is improved.
