Simple Test for Heart Function Is
Powerful Predictor of Mortality

A 1999 paper1 reports that “a delayed decrease in the heart rate during the first minute after graded exercise, which may be a reflection of decreased vagal activity, is a powerful predictor of overall mortality, independent of workload, the presence or absence of myocardial perfusion defects, and changes in heart rate during exercise.” A similar result was reported by a different group in a 2006 paper,2 which found that the deceleration capacity of heart rate is “a powerful predictor of mortality after myocardial infarction” and is more accurate than conventional measures of heart-rate variability.
