Simultaneous Analysis of Heart Rate Variability and Myocardial Contractility During Head‐Up Tilt in Patients with Vasovagal Syncope

Cardiac Autonomic and Inotropic Changes in Vasovagal Syncope. Introduction: The aim of this study was to evaluate simultaneously cardiac autonomic activity, through heart rate variability (HRV) analysis, and cardiac inotropic changes during head‐up tilt (HUT) in patients with recurrent vasovagal syncope.
