Atrial Fibrillation
"My doctor started me on Metoprolol after cardiac ablation for Atrial Fibrillation. It actually made my heart rate worse. I was waking up at 2am-5am every single morning in tachycardia of 115-148 bpm. I stopped taking Metoprolol, and have been in normal sinus rhythm ever since. I am glad it works for most, it just did not work for me. Atrial Fibrillation and/or tachycardia is horrible, and they have got to come up with something new for us sufferers soon."
