I can understand how you feel. I had an ablation in January, the first couple of months I would feel the start of svt's and get all upset about the procedure possibly being a failure. I am now 4 month post and everything has finally calmed down. Keep thinking positive and try and ride out the healing process. The people on this site can provide alot of encouragement,
Sounds like you know a lot more about what to expect than I do, but what I know is in agreement with what you say... it will pass, be calm and optimistic. Call your doctor too if that will help. Sometimes one doesn't have to talk with the doctor, a call to the office will get some encouragement via a nurse or other medical associate.
