The REVERT Maneuver was initially described by Appelboam et al. in The Lancet in 2015 as a way to more reliably induce forced valsalva to convert SVT. You can learn how to perform it in seconds, but I highly recommend you check out the original trial, because it was a very well done RCT.

This maneuver works because in addition to stimulating vagal pathways by blowing into a closed system (a medication syringe) and increasing intrathoracic pressure – you also dump extra blood into the thorax by raising the legs, which further increases intrathoaracic pressure, making the vagal response all the more potent.
