My husband has chronic a-fib and CHF. 2 cardioversions worked temporarily, but after a few days he'd be back in a-fib. He had an 11 hour ablation a few months ago, but at the 6 week point was back in a-fib and once he's fully healed will have another ablation. My question is: how does eliminating the area of the heart responsible for a-fib somehow force normal sinus rhythm? I worry that if they scar too much of the heart area, he won't have any rhythm at all! Isn't an a-fib rhythm better than no rhythm at all?
Sorry you too are going thru this vic......it sort of worried me when you used the word "scar" because i am in high hopes that the doc didn't "burn" the areas responsible. That has been determined to in the interest of the patient to cauterize the passageways because scar tissue builds up where they zap the pathways causing new issues of new pathways starting because of the scar tissue raising above the base of the heart which makes alot of sense. The way most docs now do it is either via freezing or cryo or RF or radio frequency waves because in either of those instances there is no scarring. Its not so much eliminating the area of the heart vic what happens is that our hearts beat in a very specific pattern...from top to bottom along an electrical pathway that when the electrical hits the bottom of the heart basically is spreads out a little..what happens with atrial fib is that instead of the pathway being straight or fairly straight the electrical patterning decides to basically veer off course and cannot do its job because it is re routing itself and many times people like me for instance have additional pathway that shoot off of the main pathway and those have to be blocked and re routed back where it belongs...thing of a lightening bolt vic....the heart is the main pump of the body and it runs off of electrical activity and the brain of the heart is the AV/Sinus node of the heart which the electrical is basically talking to and firing telling it to pump for us that is why that area of the heart is called the no fly zone..docs stay clear of the brain of the heart because if it is accidently touched or hit by the catheter it shorts out the brain, it can't take directions anymore and then people can end up w. a pacemaker. When you say isn't atrial fib better then no rhythm at all would mean that w. no rhythm death would occur basically because it is the rhythm that keeps us alive. Atrial fib has its own worries too...clot issues, etc. The main thing is to be sure that the docs are not burning the heart vic....the other thing is that it seriously takes up to 90 days to even know if its a fail or not and not before and for the patient it can take up to the six month mark before all of the random episodes of tach, atrial fib, etc. start slowing down and becoming less and less for myself i had an extreme case of atrial fib and it took me to the four month mark for the symptoms to stop but my heart doc put me on a low dose of antenolol to take the edge off for my heart so that it didn't happen with the weird atrial fib coming back at me and it definately worked. He later gave me a pocket pill called Mutaq in case the antenolol didn't work so that i could convert myself at home rather then running back and forth to the E.R, to get converted which we all know is not not fun. Question everything vic and if they are burning you have a right to be concerned. I would do a little more research my friend.
