atrial fibrillation
"I have taken Toprol XL for years for atrial fib and tachycardia. I get very anxious at times without this and my blood pressure and heart rate will race with the chance it could convert to AF. Lately however, my heart rate has fallen to low 40's taking only 10 mg and my doctor has taken me off it completely. I feel very shaky now. My hands visibly tremble and I notice I get more of an adrenaline rush when under pressure or fear. I need something to replace this because I don't want to experience AF again and I need something to calm me down. Any suggestions would be appreciated."
