atrial fibrillation
"I was diagnosed with AF about three years ago.  Step one was defib which was ineffective.  Step 2 was sotalol plus defib, which got me back in rhythm but slowed my pulse into the fourties.  I couldn't walk up a flight of stairs!  So they added a pacemaker which keeps my pulse at or above 60.   All is well now, and the advantage of this pacemaker is that it stores any episode and reports back to the doctor through a transmitter in my home as well as at my semi-annual appointment.  I am a very happy camper!  74 year old male."
