Heart rate variability: Standards of measurement, physiological interpretation and clinical use
Task Force of the European Society of Cardiology and the North American Society of Pacing and Electrophysiology (1996) Heart rate variability: Standards of measurement, physiological interpretation and clinical use. Circulation 93:5 1043–65.
First Paragraph: The last two decades have witnessed the recognition of a significant relationship between the autonomic nervous system and cardiovascular mortality, including sudden cardiac death. Experimental evidence for an association between propensity for lethal arrhythmias and signs of either increased sympathetic or reduced vagal activity has spurred efforts for the development of quantitative markers of autonomic activity.
- Provided standardization of the frequency bands referred to in spectral analysis of heart rate.
