Yesterday I Went for my pre assessment, prior to my second cardio version today and my heart was in AF, as it had been for months. Today I got as far as the ecg before they gave me the cannula for the treatment and my heart chose today to go back into rhythm. Great I hear you say, not me, the shock was huge and the thought of a long waiting list for another cardio version, once it went back into AF was one of dread. Once I got used to it, I was more pleased. Has anyone else had similar? Also,I am on the waiting list for an ablation, will they still do that?
