Thanks Karen. My new EP doctor, unlike the others, will not promise 100% recovery. Although, my last ablation was in 2007. He explained to me, how far they have progressed in almost 5 years. He does however, feel that , if in fact it is a success the 4 th time, that I would have have better quality of life. I asked my GP yesterday, if strokes are still a risk for SVT patients, while on preventative meds. His response was, yes. So, i'm trying to educate my self, on the Pros and Cons. Thanks, take care.
