Does Your Heart Stop When You Hiccup?

The heart does not skip a beat when an individual hiccups. A hiccup is an uncontrolled spasm of the diaphragm, which is the muscle between the chest and the abdomen. The intake of breath is cut off by a shutting of the vocal cords or glottis, states WebMD.

Hiccups are very common and usually go away after a short period of time. If they last for extended amounts of time, it may mean there is an underlying medical concern. In some severe cases, doctors may prescribe medications including metoclopramide, chlorpromazine and haloperidol, reports Hiccups are caused by a full stomach.
