Please place your trust in your Doctors. I'm sure there have dealt with situations like yours hundreds if not thousands of times. We all feel we are the only ones. I know I do. I have had 3 ablations.. you are always asleep for an ablation, well I was anyway, unless your doctor told you differently.... please don't worry about . Please don't worry about inducing tachycardia. I had this done and it was so short I didn't even notice.... This is all so scary for you but you have been through so much worse. You can do this.👍
