Abstract
Activities within the sympathetic and parasympathetic limbs of the autonomic nervous system were estimated in control subjects and in patients following myocardial infarction, using heart-rate-variability analysis. Autonomic balance was represented as the ratio of sympathetic to parasympathetic activity estimates. Results indicated that automatic imbalance is detectable in patients with recent myocardial infarctions (<6 wk previous) but not in those with older infarctions (>1 yr).
