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]. Allison Michaud, PhD, Eddy Lang. Leg lift Valsalva maneuver for treatment of supraventricular tachycardias. CJEM 2017; 19(3):235-237 [2].
Objective:
To verify the efficacy of the modified Valsalva maneuver in SVT in Chinese population and simplify the operation process further.
