Diurnal variations of neurocardiac rhythms in acute myocardial infarction
Abstract
To determine the diurnal pattern of cardiac autonomic tone in acute myocardial infarction (AMI), this study examined the power spectrum of heart rate (HR) variability in 24 patients during a single 24-hour segment within 4 days of AMI. Patients were nonrandomly allocated to a group (n = 14) without autonomic drugs and to a group (n = 10) already receiving beta blockers at the time of AMI. With use of autoregressive modeling, the power spectrum …
