Embodiment Construction
[0054] In this embodiment, a method for classifying arrhythmia based on multi-lead information fusion includes the following steps:
[0055] Step 1. Obtain the original ECG signal and its corresponding label y, and down-sample the original ECG signal to obtain the sampled ECG signal; perform clipping or zero padding on the sampled ECG signal to obtain the preprocessed ECG signal X , and the preprocessed ECG signal X contains d leads.
[0056] Step 1.1. Obtain the original ECG signal and its corresponding label required for the experiment from the public database of the China Physiological Signal Challenge (CPSC) 2018. The public database of CPSC 2018 provides 6877 12-lead ECG records with a time length ranging from 6 seconds to 60 seconds. Records were collected from 11 hospitals with a sampling rate of 500 Hz. These ECG records contained nine rhythm types, normal rhythm and eight arrhythmias, as shown in Table 1.
