question: I have been diagnosed with chronic cough a few years ago (saw a top respiratory specialist for 10 months and all the tests did not show I had asthma or any other problem). Also may years ago we lived through a stressful period and I starte having an irregular heartbeat - was on a beta--blocker for the next couple of years then went off it. Presently I am on no medication whatsoever; I just take a multi vitamin/mineral capsule each day and a magnesium supplement. This past year I have been having irregular heartbeats again - and (finally!) my question is - can a chronic cough in itself cause an irregular heartbeat - thank you..
