I had a Cyro Ablation on March 16 of this year so it has been 5 months. (Today is August 19.) On April 13, I was taken off Flecainide and then put on a two-week Zio monitor on June 30 to see how effective the ablation was at least at that point. On June 23 I had one Afib episode lasting about 4 hours. Then on July 8, I had another Afib episode lasting 6 hours and so, was re-started on Flecainide but on a lower dose. (50 mg. twice daily.) which has worked so far.
I asked my EP, "Why bother to have the ablation if Afib can still occur? He said the main purpose of ablation is to hopefully reduce the incidence of Afib, not necessarily to end them. I know this is true and that many people have had multiple ablations. I asked him about the possibility of a second ablation and he noted that, because my episodes always occur at night, they may be related to my Sleep Apnea so, "before going back in", he wanted to test that hypothesis by having me successfully establishing a regular CPAP regimen and going off Flecainide. I just got a new BIPAP machine and am getting started. This hypothesis would then be tested by taking me off the flecainide again while on that treatment.
All that being said, my question is: Today, at the grocery store, I lifted a very heavy bag of liquids - water, etc. into the trunk and felt that something in my chest was really strained. My question is can we damage or undo the beneficial work done by our EP by overdoing? I hope I didn't because, since back on the low dose of flecainide, I have been doing very well.
Thank you.
