Iwas also diagnosed with Afib in Nov. 24. I was told I had to be on blood thinner for 4 weeks before I could get a cardioversion! I begged to get it sooner! Cardioversion on 12/04 and did okay for 5 months! Mother's Day had a 5 hour episode and a week later another episode lasting 8 hours! I insisted on being referred to an electrophysiologist! I will be begging for an ablation! Repeated occurrences can mean the ectopic foci are spreading! I take Cardizem, blood thinner, Magnesium, have controlled B/P, no heart conditions, drink no alcohol, drink 1/2 caf coffee, no diabetes, not overweight, exercise every day, nothing to explain this condition except age! I am totally disgusted and fed up with the fear of another attack! I want my best chance at a decent outcome and I am seeking a pulse field ablation ASAP!
