Heart Rate Variability, Catecholamine and Hemodynamic Responses During Rest and Stress in Coronary Artery Disease Patients: The PIMI Study
Abstract
Altered cardiac autonomic balance has been shown to be a predictor of adverse cardiac events in patients with cardiovascular decease (CAD). Alteration of the sympatho-vagal balance of heart regulation may be more evident during periods of mental stress. The high frequency (HF) component of heart rate variability (HRV) is a marker of the parasympathetic regulation of the heart. The meaning of the low frequency (LF) component of HRV is controversial, but it mayrepresent the sympathetic modulation of heart regulation.
