An extracted characteristic vector can be better present difference of the ECG signals, and disadvantages of utilizing only a waveform analytical method or a template analysis method are avoided. The invention further comprises the electrocardiogram equipment comprising the method. The method is advantaged in that the characteristic vector extraction algorithm is simple and easy for realization, the operation speed is fast, classification accuracy is high, and the method is suitable for a wearable electrocardiogram real-time monitoring automatic analysis diagnosis system.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a heartbeat type classification method, device and electrocardiograph. Background technique [0002] Cardiovascular disease remains the leading cause of death worldwide. The human electrocardiogram signal records the depolarization and repolarization process of heart cells, reflecting the generation and conduction process of cardiac electrical excitation. The evaluation provides an important basis. In modern medicine, the automatic detection and analysis of electrocardiogram (ECG) is of great significance for the analysis and diagnosis of cardiovascular diseases, and it is also the core component of many ECG monitoring equipment with automatic analysis and diagnosis functions. Therefore, automatic detection and analysis methods based on ECG have been extensively studied. [0003] There are certain differences in the existing classification methods of heartbeat types. T...

Problems solved by technology

[0003] There are certain differences in the existing classification methods of heartbeat types. They are analyzed according to the characteristic waveforms in the electrocardiogram. The main parameters of the characteristic waveforms are: QRS complex wave width, waveform amplitude, waveform interval, waveform Morphological direction, etc. These characteristic waveform parameters are compared with the preset fixed judgment threshold, and the corresponding heartbeat type is judged according to the comparison result with the threshold, such as: sinus heartbeat, premature ventricular beat, atrial heartbeat, etc. However, such The method selects a fixed threshold as the basis for judgment. The selection of the threshold is highly dependent on clinical experience and analysis experience, and the universality is not sufficient. It is difficult to effectively select the threshold, and it cannot effectively distinguish the heartbeat types with insignificant differences.
