Abstract:
The REVERT trial was a randomized multicenter trial that investigated the efficacy of using a modified Valsalva maneuver for the reversion of stable supraventricular tachycardia back to a sinus rhythm. Although no improvement in discharge to home from the emergency department (ED) or ED length of stay was observed, the REVERT trial demonstrated that the modified Valsalva maneuver was superior to the standard Valsalva maneuver. The modified Valsalva maneuver should be considered first-line treatment for patients who present with a stable supraventricular tachycardia. A case presentation illustrates the methodology for utilizing the modified Valsalva maneuver to treat supraventricular tachycardia in a hemodynamically stable patient who presents to the ED.

Avoidance Learning and Learned Helplessness
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...
