Link Between Elevated Long‐Term Resting Heart Rate Variability and Pulse Pressure Variability for All‐Cause Mortality

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Elevated long‐term systolic blood pressure and resting heart rate (RHR) variability are suggested to amplify the risk of all‐cause mortality (ACM). However, the link between increased RHR and pulse pressure for ACM remained unclear.
