Wow I'm sorry for my horid spelling I really wasn't paying attention. But anyways yes she had the bypass surgury but she also suffers from high blood pressure and type 2 diabetes. Could this contribute? When she really starts to try to become active a sudden pain in her chest will start and she has to rest for several minutes and take some medication. I think that is related to the opperation but I'm not sure about the skipped beats. She just turned 51yo.
I don't understand what still affects your mother, something related to the bypass surgery?
Most people, well at least a lot of them, over 50 have increased heart rhythm abnormalities. My bottom-line here is a few skipped beats is most likely not dangerous or even serious. still it is worth getting a doctor to listen to it, perhaps to do an EKG. Given your mother had bypass, she must have a cardiologist contact, that's the best specialist to have check the skip.
