Background: Supraventricular tachycardia (SVT) is not an uncommon condition in the emergency department. Epidemiologically, SVT has an incidence of 35/100,000 person-years in the United States.2That is roughly 89,000 new cases per year. The Valsalva maneuver is a recognized treatment for SVT, but has a low success rate (5-20%). 3,4,5 The REVERT trial showed an increase in cardioversion of SVT using a modified Valsalva maneuver, but this was done with a manometer, and adjustable bed, which may not be available in many settings.
