Does exam stress alter heart rate variability parameters in healthy medical students?
Exam stress did not significantly alter heart rate variability in medical students, suggesting physiological adaptation to frequent exams in a system-based curriculum.
E. A. M. Shokr (2015) conducted an observational in Healthy (n=50). Exam stress vs. Post-exam period was evaluated on Time and frequency domain parameters of heart rate variability. Exam stress did not significantly alter time and frequency domain parameters of heart rate variability in healthy medical students compared to the post-exam period.
