Embodiment 1
[0028] figure 1 The method flowchart of an embodiment of the method for detecting ventricular / supraventricular premature beats provided by the present invention may be executed by a detection device integrating digital signal acquisition and processing functions. Such as figure 1 As shown, the ventricular / supraventricular premature beat detection method specifically includes:
[0029] S101. Acquire an electrocardiogram signal to be detected, and perform preprocessing.
[0030] In this embodiment, the electrocardiogram signal to be detected is preprocessed by using a band-pass filter such as a frequency band of 0.67 Hz to 40 Hz to suppress low-frequency drift and high-frequency noise interference in the signal, thereby obtaining a relatively pure ECG signal.
[0031] S102. Extract the RR interval corresponding to each beat in the preprocessed electrocardiogram signal, and mark the beat corresponding to the RR interval smaller than the fixed percentage of the RR interval of t...
