Excerpt
Excerpt: Heart rate variability (HRV) is mediated by the interplay of the sympathetic and parasympathetic branches of the autonomic nervous system (ANS). Quantitative assessment of the HRV frequency spectrum derived from the electrocardiogram (ECG) provides a reliable, noninvasive method to assess autonomic control of cardiac activity (1,2). HRV is of particular interest because of its value in predicting long-term cardiac morbidity and mortality. Reductions in specific components of the HRV frequency spectrum are prognostic for the development of heart disease in large prospective cohort studies (3?6) and in studies of coronary artery disease, postinfarction risk, and sudden cardiac death (7?9).
