Abstract

Clinical question: Valsalva maneuver is a recognized treatment for supraventricular tachycardia, but in clinical setting it has a low chance to achieve successful cardioversion. Studies suggested that the postural modification of valsalva maneuver may improve the rate of cardioversion. We further modified the maneuver and conduct a multicenter randomized controlled trial to test its efficacy.

Objective: To verify the efficacy of the modified Valsalva maneuver in SVT in Chinese population and simplify the operation process further.
