Yes, the first one worked great for 3 months, then I went into flutter, then ablation 2, then SVTs started with passing out as I went into them, then ablation 3, didn’t work to stop SVTs so one more time! My heart just kept finding new pathways to misbehave I guess. I started afib originally in my early 20’s, paroxysmal. Seldom enough then to just wait the episodes out, for usually up to 5-8 hours. Then it got more frequent as I got older, so began med, it kept me ok for 12 years. Then I broke through that one and first ablation done, so I’d be off meds and no more afib! Did not work out that way…
