Thanx,Jerry..... my hubbie is wanting me to go to ER or urgent care as he is worried about my coughing impacting my heart and starting up the a-fib... he is a tad over protective!! However, I can be too laid back about things and just "wait" and see what's happening. He coughed for 2 weeks and was pretty sick; however, has no heart probs. so thanx for your comments....I read them to him.
I think any physical strain can add to the stimulus for all arrhythmia, so my guess is "yes", but, I don't believe coughing will cause any permanent change in your condition.
