Atrial Fibrillation (AFib) Support Group
Atrial fibrillation (AF or afib) is an abnormal heart rhythm (cardiac arrhythmia) which involves the two small, upper heart chambers (the atria). Heart beats in a normal heart begin after electricity generated in the atria by the sinoatrial node spread through the heart and cause contraction of the heart muscle and pumping of blood.

Tachycardia following AF ablation
BORDEAUX, FRANCE. As more complex forms of
Professor Michel Haissaguerre and colleagues at Hopital Cardiologique du Haut-Leveque have just published a two-part report on the mapping and ablation of AT following AF ablations. They now consider this AT a natural progression on the road from afib to normal sinus rhythm and make the following somewhat surprising statement:
Conversion of AF to one or more intermediate ATs is an important step in the maintenance of lasting sinus rhythm. Recurrence of AF is rarely seen after this conversion occurs, while it is the most common recurrent atrial arrhythmia when it does not.
In other words, experiencing atrial tachycardia after an AF ablation is a good rather than a bad sign.
AT can be macroentrant or focal in origin and is often associated with gaps in the lesions made during the AF ablation. The origin of the AT is established by careful electrophysiological mapping. The first step involves checking that the isolation of the pulmonary veins is complete and, if it is not, filling in the gaps with fresh lesion lines. The second step involves the assessment of cycle length variability to see if the AT is of focal origin, while the third step involves checking for macroentrant circuits, particularly around the mitral valve and in the roof of the left atrium.
A recent study carried out by the Bordeaux group found that 46% of AT was macroentrant, while the remaining 54% was focal in origin (including localized reentry at the pulmonary vein junctions). The average mapping time to determine the origin of the AT was 10 minutes and 97% of all ATs were successfully mapped.

So sorry to hear that things are not going as well as you had expected but Petey's new is good. Please give it a little more time.
Moy...
Once again you have come up with a very helpful article thru all your searches!! Thanks a LOT!!
It does say another ablation is the cure. I don't know if I want to go thru that esp since the ablation caused the AT.
Very interesting. Obviously mine is not the one which disappeared in a few weeks since I'm 3 mos out.
The nurse practitioner did mention that Tikosyn isn't very effective against AT. So will see what the doc says about keeping me on it. However, if I develop a lot of AF off of it, I will have to be rehospitalized , like Moy, to get back on it. No fun.
There are so many uncertainties in dealing with this a fib. It's enough to drive you insane by itself!!
Thanks for the encouragement and Petey, thanks again for the very helpful article. Is France THE place for ablations???
Jim
Bordeaux i believe is THE place to go in Europe. Almost considered
it , since I'm German and I'm familiar with the region and the center. However, unless you're French, you have to pay about 35K US dollars out of pocket. I checked a few years ago, right after I was diagnosed. Could be more now, or maybe less due to the strong dollar.
It was too cumbersome for me. I've lived in the States too long, my family is here and I have American insurance and I don't remember much of my high school French anymore.
But yes, i consider them one of the top centers in the world and their research and experience is absolutely renowned
Sanibel-good to know about France. I couldn't afford to go there for sure!
They found a lesion on my spleen while doing the MRI. Yet another thing to worry about!!
I surely hope it doesn't come to that. Thanks for your encouragement!!
The event monitor happened to catch one AT. But who knows if some of the other "runs" I feel are not AF?
This whole situation is rather depressing...
I'm very grateful Petey is able to pull up all these helpful articles!!!
Has anyone else heard of this?
I'm sure with all the problems I've had, my heart will do its best to defy me! I can only hope I'm stronger than it is!!! :)
