Association Between Phasic Vagal-Mediated Heart Rate Variability and Momentary Exhaustion in Daily Life.

ABSTRACT: Stress-related chronic exhaustion can be predicted longitudinally by reduced basic vagal tone (i.e., vagally-mediated heart rate variability [vmHRV]). However, little is known about the relationship between phasic vmHRV and momentary exhaustion in daily life. To examine this relationship, this preregistered study used ecological momentary assessment (EMA) in a sample of N = 151 healthy participants (age = 22.17 years [SD = 4.98 years]; 14.57% male) for three consecutive weekdays. Exploratorily, we examined if individuals with higher chronic exhaustion would show different patterns of phasic vmHRV when perceiving acute stress. We analysed data on momentary (emotional, cognitive, physical) exhaustion, perceived acute stress, ambulatory ECG data and adjusted for relevant covariates (e.g., age
