文摘
Two patients are described with reproducible cardiac asystole post-exercise. No structural heart disease was demonstrable. At autonomic function testing no abnormal responses were noted. Also, head-up tilt tests were normal. However, electrophysiologic testing and heart rate variability during 24-h Holter monitoring were indicative of a high vagal tone in both patients. The findings suggest that post-exertional asystole may not be due solely to a vasovagal mechanism; excessive rebound vagotonia per se may also play a role.
