I am going in for a cardiac ablation in 2 weeks and was feeling only slightly nervous until I read some comments about how the burning hurts and is very intense. I know I will be only mildly sedated and I have an overactive vagal response so am worried about that. It probably doesn't help that I also have an anxiety disorder : ( I know I can't live with these continuous runs of pvcs anymore as it is limiting my life drastically. If anyone could shed any light on this, I would greatly appreciate the support.
