Diagnosis of cardiovascular abnormalities from Compressed ECG: A data mining based approach

Abstract

Usage of compressed Electrocardiography (ECG) for fast and efficient telecardiology application is crucial, as ECG signals are enormously large in size. However, conventional ECG diagnosis algorithms require the compressed ECG to be decompressed before diagnosis can be applied. This added step of decompression before performing diagnosis for every ECG packets introduces unnecessary delays, which is undesirable for cardiovascular patients. In this paper, we first used an attribute selection method that selects only a few features from the compressed ECG. Then we used clustering techniques to create normal and abnormal ECG clusters. 18 different segments (12 normal and 6 abnormal) of compressed ECG were tested with 100 % success on our model. This innovative data mining technique on compressed ECGs, now enables faster identification of cardiac abnormality directly from the compressed ECG, resulting in an efficient telecardiology diagnosis system. ©2009 IEEE.
