atrial fibrillation
"I was on Toprol XL for many years and one day it just stopped working. I had a procedure and things got worse. I started on Propafenone my heart is doing much better but I have a bad taste in my mouth that is better than heart problems. I also seem to have difficulty breathing. It is like I am to tired to breathe but I am hoping that feeling goes away because it is wonderful to have my heart beating regular."
