Vagal maneuver success in AVRT/AVNRT depends on circuit properties; extends mechanistic insights but leaves optimal use hypothesis-generating.
What are the electrophysiological mechanisms and determinants of vagal maneuvers for the termination of paroxysmal supraventricular tachycardia?
The success of vagal maneuvers in terminating PSVT depends on both the patient's autonomic response and the specific conduction properties of the reentrant circuit.
Wen et al. (1998) studied this question.
