Abstract

A wide variety of algorithms have been devised for the compression of ECG signals during last five decades. These techniques have not only brought about a considerable reduction in ECG data volume for storage but also enabled economic and efficient transmission of data for distant analysis. The main purpose of this paper is to present an overview of ECG compression methods especially the direct data compression methods as well as the various performance measures governing the effectiveness of these methods. Broadly ECG compression methods have been classified as direct compression method, transformation method and parameter extraction method. However, this paper addresses the various direct data compression techniques such as AZTEC, Modified AZTEC, Turning Point Technique, CORTES, Fan, SAPA, Entropy Coding, Peak-Picking, Cycle to Cycle compression and ECG data compression by DPCM.
