I had an ASD repair in 1995 with flutter beginning in 1997. After many cardioversions and intolerance to antiarrythmics I travelled to Oklahoma City for an ablation. The albation was, at first, successful then flutter returned after a week. Again travelled to OKC for another ablation but, this time, the arrythmia could not be induced ~ therefore, no ablation. I was then put on Acebutolol and my life returned to normal. But last year I experienced extremely slow heart rate (40-45 bpm) so (at the suggestion of my Dr.) tried to discontinue the BB but experienced new and disturbing afib. Now, after six years on the beta blocker (100mg x 2 Acebutolol) I find myself extremely depressed and unable to pull out of it. I'm wondering if long term use of this beta blocker may be causing my depression. Thanks, Heartlight
