Embodiment Construction

[0114] Such as figure 1 As shown, the present invention is an intelligent analysis method for supraventricular premature beats based on the attention conversion mechanism, which includes the following steps.

[0115] S1: Obtain the ECG data to be identified; in the specific implementation, about 100,000 data of the dynamic electrocardiogram every 24 hours are recorded as a set of ECG data to be identified. When performing identification, each time a set of data to be identified is input for identify.

[0116] S2: Based on the ECG data to be identified, draw the RR interval scatter diagram of the full data time; in the specific implementation, use the continuous RR interval in the long-distance electrocardiogram as the ordinate and the time as the abscissa to make scatter points in the Cartesian coordinate system Bar chart; refer to the accompanying drawings in the manual Figure 5 , is an embodiment of the time RR interval scattergram of the electrocardiogram.

Abstract

The invention provides a supraventricular premature beat intelligent analysis method based on an attention conversion mechanism, and the method can improve the recognition accuracy of supraventricular premature beat heart beats, greatly saves the manual workload, and improves the recognition efficiency. According to the technical scheme, all RR interval stationary heart rate segments are found based on a time RR interval scatter diagram, all the RR interval stationary heart rate segments are connected based on a forward and reverse propagation algorithm, and a dominant heart rate curve corresponding to electrocardiogram data to be recognized is obtained; and constructing a rhythm classification and recognition model based on a convolutional neural network, recognizing the rhythm type of each heart beat, and judging the heart beat of each supraventricular premature beat type in the electrocardiogram data to be classified based on the dominant heart rate, the RR interval deviation degree, the rhythm type and the QRS wave form of each heart beat.

Description

technical field [0001] The invention relates to the technical field of medical artificial intelligence, in particular to an intelligent analysis method for supraventricular premature beats based on an attention conversion mechanism. Background technique [0002] Supraventricular premature beat refers to the premature contraction of the ectopic rhythm point originating above the ventricle, which is a common arrhythmia phenomenon in clinical practice. An electrocardiogram (ECG) is a graph formed by recording the changes in the electrical activity of the heart every cardiac cycle from the body surface. A variety of heart diseases in humans can be characterized by an electrocardiogram. Under normal circumstances, the number of heartbeats within 24 hours reaches 100,000. In the existing clinical diagnosis methods, it is necessary to find characteristic ECG waveform data in a large amount of dynamic ECG data, and then perform follow-up analysis and diagnosis based on these charac...
