PAT: You had paroxysmal atrial tachycardia which may be triggered by anxiety, stimulants, overactive thyroid, and in some women, the onset of menstruation. Your coughing was like a valsalva maneuver which stimulates a nerve and slows the heart. This is not a disease and is seldom life-threatening. The episodes are usually more unpleasant than they are dangerous, and the prognosis is generally good.
