Sotalol
"Been on sotalol for 8 months now- had 2 relapses of AF. Had pacemaker implanted to stop bradycardia - on low dose of 80mg per day. Tried several beta blockers all caused low BP and heart rate. Sotalol does not affect BP. Side effects come and go - main ones ear noises - weight gain ( 6kg) - visual disturbance and suppression of heart rate when exercising."
