Violent Hiccups: An Infrequent Cause of Bradyarrhythmias

By William M Suh and Subramaniam C Krishnan

Abstract

A hiccup, or singultus, results from a sudden, simultaneous, vigorous contraction of the diaphragm and inspiratory muscles, accompanied by closure of the glottis. Hiccups can be associated with bradyarrhythmias. The mechanism of this phenomenon is likely hiccup-induced Valsalva maneuver and increased parasympathetic tone. We present a case of a patient with violent hiccups producing a bradyarrhythmia.[WestJEM. 2009;10:176-177.
