Thanks for your question on Healthcare Magic.
I can understand your concern.
Yes, these two events might be related to each other.
CABG (Coronary
artery bypass grafting) patients are at increased risk of
arrhythmia (rhythm disturbances in heart). So your skipped beats are likely due to arrhythmia.
Some arrhythmia can also cause sudden gasp of breathing. And this is considered as serious event.
So in my opinion, you should consult your cardiologist again and discuss about this event.
You will need repeat ecg, 2d echo and Holter monitoring (24 hours continuous recording of ecg).
On the basis of these reports, suitable anti arrhythmia drug will be started.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
