Abstract :
This research is aimed at detection and evaluation of beat-to-beat T-wave alternans in electrocardiogram. To reveal diagnostic features related to T-wave alternans, variations in amplitude and shape of T-waves from synthetic and clinical recordings were explored by means of time-domain analysis, Poincare plots, and principal component analysis together with clustering analysis.
