T Wave Analysis: Potential Marker of Arrhythmia and Ischemia Detection-A Review

T wave is the end potential waveform or segment of cardiac cycle. It is basically originated by the different layers of ventricular myocardium and their differences in repolarization time. This study analyzes the conventional techniques and automatic popular methods associated with T Wave Alternans (TWA) and their approaches towards ischemic and arrhythmic interventions. This review work is divided into two major parts i.e. (i) Analysis of T wave: association of T wave with ischemia and arrhythmia (ii) T wave detection techniques. This analytical literature survey also leads to the conclusion, where the importance of T wave analysis significantly inculcates ideological researcher and clinical mindset for approaching critical cardiac diseases in multimodal approaches.
