Ambulatory and Challenge-Associated Heart Rate Variability Measures Predict Cardiac Responses to Real-World Acute Emotional Stress

摘要

BackgroundHeart rate variability (HRV) measures homeostatic regulation of the autonomic nervous system in response to perturbation, and has been previously shown to quantify risk for cardiac events. In spite of known interactions between stress vulnerability, psychiatric illness, and cardiac health, however, to our knowledge this is the first study to directly compare the value of laboratory HRV in predicting autonomic modulation of “real-world” emotional stress.
