Well, tomorrow is my day with catheter ablation. It was scheduled for two weeks ago, but my doc put it off until tomorrow. I am glad he didn't put it off any longer than he did because my shortness of breath is getting worse. I just hope it works as well for me as it did for some of you. I have learned a lot about AFIB. I thought it was just an irregular heart beat. I had no idea it could take so many forms. Mine is electrical and the atrial portion of the heart doesn't beat at all - it just spasmodically flutters. I guess the ablation removes the malfunctioning nerve tissue.
