The Abilit of Several Short-term Measures of RR Variability to Predict Mortalit After Myocardial Infarction

Abstract

Background. We studied 715 patients 2 weeks after myocardial infarction to test the hypothesis that short-term power spectral measures of RR variability (calculated from 2 to 15 minutes of normal RR interval data) will predict all-cause mortality or arrhythmic death. Methods and Resuls.We performed power spectral analyses on the entire 24-hour RR interval… (More)
