I had Atrial flutter that would just about bring me to my knees and when it happened, I could not do much. Came on all of a sudden 3 days after 9/11 while walking (usual 3 miles) with my wife and dog. (I wonder if living 30 miles from 9/11 and seeing the smoke on the horizon had anything to do with it??) Went through 5 cardioversions attempting to shock it back to good rhythm and 4 different meds to try to control it, to no avail. (This was over a period of 8 months. Finally got referred to a good EP who did the Catheter Ablation. Took about 5 hours. I am on no meds now, and 98% of the time everything works ok, but it gets a little squirrelly once in a while, but goes back to good rhythym... Ablation procedure was not that bad, catheters in both sides of the groin, plus in the neck. Really cold in the room and the anesthesia gave me a horrible headache and hangover for a couple of days, though.... Just wanted you to know what it is all about.....Thanks Oh yeah, I got the ablation on May 2, 2002, and got downsized 2 weeks later. Nice company, the big computer company with the first letter I. Been hit or miss working since.
