What the study found
Heart-rate variability measures differed during procedures and across training periods in a small group of interventional cardiologists. The objective and questionnaire changes did not correlate in the reported comparison.
Participants and protocol
Six cardiologists were observed during two periods of 10–14 days, with 217 procedures analysed using HRV recordings and anxiety questionnaires.
What this cannot establish
This is an occupational-stress study, not an endurance-training trial. Its HRV values do not define an athlete's recovery threshold, and the small observational design limits generalization.
