ResumoReduced left ventricular ejection fraction (LVEF) and late potentials (LP) are used in risk stratification after myocardial infarction (MI) [ 1 Moss A.J. Hall W.J. Cannom D.S. et al.

Recently, QT interval variability index (QTVI) has been found to predict sudden death in structural heart disease [ [3] Atiga W.L. Calkins H. Lawrence J.H. Tomaselli G.F. Smith J.M. Berger R.D.
