Sometimes I get a strange feeling in my chest and then it makes me cough.  It almost feels like my heart stops and then the cough gets it going again.  It does not happen a lot and does not seem at all predictable.  Also, it does not go on for a long time, just a couple of seconds.
Thanks for your question on Chat Doctor. I can understand your concern. Ideally ECG and 2d echo should be done done first in your case. If both are normal than no need to worry about heart diseases. It could be anxiety induced as well if everything else is normal. Don't worry, you will be alright. Hope I have solved your query. Wish you good health. Thanks.
