Quote: That was after an episode of palps which I have had randomly for several years. I have learned how to manage them though, for instance, if I catch it just before if gets going and I cough really hard a couple times, I can stop it.
Amy - this kinda sounds like PAT - paroxysmal atrial tachycardia - a benign kind of arrhthymia that can be stopped by a cough, a Valsalva maneuver (think bearing down to have a BM) or by sticking your face in ice water. May or may not be related to thyroid - plenty of people without thyroid disease have this (and the tachycardia of true hyperthyroidism is constant) but hyperthyroidism does make the heart muscle "irritable" and more prone to arrhythmias, especially atrial arryhthmias. (Caffeine is not good for this either.)
