Hello, I had triple left main coronary triple bypass 5 months ago. am progressing well post op. however, started to have some palpitation symptom, pulse irregular ( skips some beats) , I had these symptoms years ago and was not treated and it went away. after surgery it did not occur , and now 5 months later , I have at times these symptoms, however, I am feeling well otherwise. exercising without problem, cholesterol and b/p and pulse all within control. is this a real concern post my bypass? due to the bypass? and does it always mean valve damage? does murmur always mean valve damage?
