Methods Study of Automatic Classifying ECG Signals Based On Wave Form Features and SVM

Objective： This paper put forward for classifying cardiac arrhythmia signals based on ECG wavcform features and support vector machine （SVM）. Methods： The time-domain feather,wavelet transform domain characteristics and higher-order cumulants of ECG signals arc defined and extracted as three types of ECG features .In this paper the SVM multi-class classifi- cation method is used in ECG for the first time. Results： The classification method is validated with the cardiac arrhythmia signals obtained from thc ECG databasc. Conclusions： SVM based ECG classification is also carried out respectively with thrcc different types of feature set.this method improvc the efficiency and prccision of classificr.
