Best of luck! Heart fixes are serious.
Went in for routine knee surgery in August, all ready to go in and they stopped because i had an irregular EKG. I had heart flutter. Bottom line on the EKG looked like a saw blade instead of the up/down normal. Had a Cardioversion in September. That's the electric shock to the heart and am OK now. Scared me because I had no known symptoms. The bad knee saved me by identifying a more serious problem. I was blessed and you will be too!
