Referring to a cough.

1. A form of fremitus (a tremor vibration in any part of the body that is detectable by palpation) similar to the vocal, produced by a cough.
2. A thrill felt by the hand when applied to the chest of a person coughing.

Fainting as a result of a coughing spell, caused by persistent increased intrathoracic pressure (within the cavity of the chest) diminishing venous return to the heart (blood returning to the heart via the great veins and coronary sinus), thus lowering cardiac output.

It most often occurs in heavy-set male smokers who have chronic bronchitis.
