I was diagnosed with Sick Sinus Syndrome - bradytachycardia a month ago and had a pacemaker implanted immediately. I was then put on Sotolol for a week, which did not control the high rate and afib. They changed to Metaprolol, which also did not control the afib. After a bad day of high rate all day long (140-150) and some low blood pressure, they added Multaq. Within half an hour, my rate went down to the 60-70 range (PM set at 60). Except for exercise, it has not been much higher for a whole week now. I'm getting an ablation in a month or so, but doing ok now. Did my strenuous 2-mile uphill bike ride today and heart went up to 130 but fairly smooth. That's what it went up to in the past for that ride.
