atrial fibrillation
"My new cardiologist discontinued my metoprolol and started me on Coreg to help control my blood pressure My heart used to pound in my chest while on metoprolol and it was quite uncomfortable. I had cardiac ablation for atrial fibrillation that  was approximately 90% successful, I still had occasional heart flutter from the AF. The Corey changed all that. My blood pressure is now in normal range and I haven't had one incident of heart flutter for two months. Coreg worked well for me and I hope it will work for you."
