I had an ablation a year ago Feb 5th. I've been having complications since the next day. My doctor told me it was normal and will pass. Well, it's getting worse. He prescribed atenlolo to me and I haven't taken it. I read somewhere that if you had an ablation and take the atenolol, it can lower your blood pressure to an unsafe level and cause more heart problems. I'm confused and conflicted. My heart hasn't healed properly and constantly dealing with my heart going nuts no matter what I do.
