T Wave Alternans Analysis in ECG Signal: A Survey of the Principal Approaches

Abstract:

The T wave alternans (TWA) is an important phenomenon not only within the clinical field but within the scientific and technological field, it has been considered an important, non-invasive, very promising indicator to stratify the risk of sudden cardiac death. Due to its microvolt amplitude and background noises, sophisticated signal processing techniques are required for its detection and estimation. In this paper we present a survey of the state of the art focusing to detect sudden cardiac death by analyzing the T wave on long-term ECG signals.
