May aid post-MI arrhythmic risk stratification; extends observational data but leaves open need for prospective validation.
Cohort (n=250)
p-value: p=0.0036
Reduced beat-to-beat heart rate variability is an independent predictor of serious arrhythmic events in patients following acute myocardial infarction.
Reinhardt et al. (2008) conducted a cohort in Acute myocardial infarction (n=250). Reduced beat-to-beat heart rate variability vs. Normal/higher beat-to-beat heart rate variability was evaluated on Serious arrhythmic event (p=0.0036). Reduced beat-to-beat heart rate variability was an independent risk factor for serious arrhythmic events at 6 months in patients with acute myocardial infarction (p=0.0036).
