<s>[INST] Hello,I recently had a triple bypass 3months ago today. I just went to cardiologist yesterday. he gave me an ekg. He looked at it and said it was a little abnormal but didnt seem real concerned. Is this something I should be worried and concerned with? Is this common after bypass surgery? I am 41 yrs old and I take lopressor.Thanks, Jacob. [/INST] hello,I have gone through your query.Thanks for using HCM.there may be pre existing ECG changes which may be picked up on follow up ECG and may not be serious.If your treating doctor has not taken it seriously you should not worry about it,My best wishesDr.Rajesh Teli,MD. </s>
