title: Analysis of heart rate variability and its application.
abstract: Heart rate variability (HRV) has considerable potentials in assessing the role of autonomic nervous system fluctuations in healthy individuals and patients. This paper reviews the analytical methods of HRV and its application. HRV is a useful parameter for predicting cardiac risk after acute myocardial infarction, and an early warning sign of diabetes neuropath in clinical medicine. In space medical studies, HRV analysis have been used to assess changes in autonomic regulation after weightlessness or simulated weightlessness, evaluate tolerance in various stress test, study regulatory mechanisms of cardiovascular system, and assess the effect of countermeasure against weightlessness.
