Classification of Multichannel ECG Signals Using a Cross-Distance Analysis.

摘要

This paper presents a multi-stage algorithm for multi-channel ECG beat classification into normal and abnormal categories using a sequential beat clustering and a cross- distance analysis algorithm. After clustering stage, a search algorithm is applied to detect the main normal class. Then other clusters are classified based on their distance from the main normal class. The algorithm is developed for both 1-lead and 2- lead ECG. Evaluated results on MIT-BIH database exhibit a classification error of less than 1% for 1-lead and 0.2% for 2- lead and clustering error of 0,2%.
