So nervous and weird ekg

Hi, Today i had lots of appts...all at once for my next tuesday, oct12 surgery. My ekg they said had a sinus rythm. has anyone else had such a thing? are they going to postpone my surgery? no one seemed to worried about it although they are going to send it to the cardiologist and im nervous. I hope its nothing terrible. If anyone knows anything about this let me know please. They didnt seem concerned at all at the hospital they said plenty of people have that. But will it turn into something worse? oh boy. I am sooo nervous but excited about my surgery. But still the skin hanging thing really concerns me. I need info on what i can do for that ahead of time so that it wont be as bad. I read that if you lose all your weight then its not a problem. Is that true? I need info...all my doc says is that i may want plastic surgery later. well i dont have money growing on a tree unfortunately so whats the next best thing? I dont want hanging skin!! thanks!! xox
