Hi all I have occasional afib, I was on a holter recently for 2 weeks and again for 48 hours… my valve is fine, heart rate and blood pressure good, took a stress test and that was fine, for some reason my cardiologist is determined to get me on, Amiodarone which made me sick and now bisoprolol. I am thinking of getting a 2nd opinion as I am hesitant to go on the beta blockers.. anyone have experience with this? Ventricular Tachycardia was detected so I have an appointment with the electrocardiologist in a few weeks.. i feel very good and can exercise. I had a mitral valve repair in 2004 August 12th will be my 19 year anniversary so far so good.
