A multicenter randomized controlled trial of a modified Valsalva maneuver for cardioversion of supraventricular tachycardias.
The American journal of emergency medicine(2019)
摘要
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.
RESEARCH IN CONTEXT:Appelboam A, Reuben A, Mann C, et al. Postural modification of the standard Valsalva maneuver for emergency treatment for supraventricular tachycardias (REVERT): a randomized controlled trial. Lancet 2015; 386 (10005):1747-53 [1].

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