A multicenter randomized controlled trial of a modified Valsalva maneuver for cardioversion of supraventricular tachycardias.Am J Emerg Med. 2020 06; 38(6):1077-1081.AJ
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.
