Journal ArticleDOI

Heart rate variability: Origins, methods, and interpretive caveats

TL;DR: In this article, the authors examined the physiological origins and mechanisms of heart rate variability, considered quantitative approaches to measurement, and highlighted important caveats in the interpretation of heart rates variability, and outlined guidelines for research in this area.
Journal ArticleDOI

Heart-rate turbulence after ventricular premature beats as a predictor of mortality after acute myocardial infarction

TL;DR: The absence of the heart rate turbulence after ventricular premature beats is a very potent postinfarction risk stratifier that is independent of other known risk factors and which is stronger than other presently available risk predictors.
Journal ArticleDOI

Risk stratification for arrhythmic events in postinfarction patients based on heart rate variability, ambulatory electrocardiographic variables and the signal-averaged electrocardiogram.

TL;DR: A simple method of assessment based on heart rate variability and the signal-averaged ECG can select a small subgroup of survivors of myocardial infarction at high risk of future life-threatening arrhythmias and sudden death.
