Valsalva Maneuver

By Richard N. Fogoros, M.D., About.com Guide

Updated July 20, 2011

Definition:

The Valsalva maneuver is a technique for transiently increasing the tone of the vagus nerve. (Increasing vagal tone can help to stop an episode of supraventricular tachycardia - SVT - or to stop a bout of hiccups.)

The Valsalva maneuver is performed by attempting to exhale against a closed airway. This can be done by keeping the mouth closed and pinching the nose while trying to breath out. This maneuver greatly increases pressures inside the chest cavity - which stimulates the vagus nerve and increases vagal tone.

Holding the Valsalva maneuver for five seconds or so will often terminate an episode of SVT or make hiccups go away.

Type of Myotonia: Thomsen's
