That is the question ! I saw my Doctor / specialist on Thursday . I see a different person every time . I'm not really sure of his name even , just that he knows what he's talking about . He began by asking me what I knew and understood about A fib ! Gulp. Let's play heart hangman he says. Not a good start. We go through the workings of the heart like I'm a 4 year old . Then we move to the pc so he can show me the stages of A Fib over a period of time on the heart. He likened it to arthritis , wear and tear . Apparently this damage cannot be picked up by any technology and only by having an ablation will the surgeon be able to determine how much is there and what needs to be done . I was not filled with hope. Plus the success rate he told me is 40-50%. Up to you he said . Another gulp . Harefield seems to be favourite if I decide to ' go for it ' . Any thoughts would be more than welcome !
