The Modified Valsalva Maneuver: Practical Treatment or Pointless Trick?

REBEL EM

Background: The REVERT Randomized Controlled Trial demonstrated the superiority of the modified valsalva maneuver (MVM) over the standard valsalva maneuver (VM) in re-establishing normal sinus rhythm (NSR) in patients with PSVT (Appelboam 2015). MVM exaggerates venous return to the heart and increases vagal outflow by elevating the patient’s legs.
