specific Embodiment 1
[0073] Such as figure 1 with figure 2 As shown, the embodiment of the present invention provides a method for recognizing premature ventricular beats based on an improved convolutional neural network, including:
[0074] Preprocessing step S101, preprocessing the ECG signal;
[0075] The truncation step S102 is to truncate the ECG signal into several heartbeat sequences, and extract the RR interval between each heartbeat and the previous heartbeat;
[0076] Calculation step S103, calculating the kurtosis value and skewness value of each heartbeat sequence;
[0077] Recognition step S104, input the heartbeat sequence, RR interval, kurtosis value, and skewness value into the improved convolutional neural network model, output the recognition result of the heartbeat to be recognized, and determine whether the heartbeat to be recognized is premature ventricular beat according to the recognition result; The heartbeat to be identified includes the second heartbeat and all subseq...
