Dynamic analysis of heart rate may predict subsequent ventricular tachycardia after myocardial infarction

Am J Cardiol. 1997 Sep 15;80(6):779-83. doi: 10.1016/s0002-9149(97)00516-x.

Abstract

Dynamics analysis of RR interval behavior and traditional measures of heart rate variability were compared between postinfarction patients with and without vulnerability to ventricular tachyarrhythmias in a case-control study. Short-term fractal correlation of heart rate dynamics was better than traditional measures of heart rate variability in differentiating patients with and without life-threatening arrhythmias.
