AV node ablation and cycling
Great to find this web site and forum. Quick background: I am a 68 year old male who is an avid cyclist (about 150 miles/week). I have had A-fib for approximately 20 years. My second ablation in 2014 gave me 6 years of relief and joy with an Afib burden of <5% and using a simple PIP approach to convert after brief episodes. Otherwise, no medication. Unfortunately since Feb. 2021 I have been in afib almost constantly with no help from drugs and 2 cardioversions that were short lived. I had my 3rd ablation this past week. All past ablation sites were found to be still durable, so the current site was mapped and ablated along with some additional "preventive" lines. Came out of the procedure in sinus rhythm but reverted to afib in 48 hours. Since then I have converted back briefly but then back into afib. On follow up with my EP, the possiblity was raised of an AV node ablation and of course, PM. Which has sent me here.
The EP has suggested a leadless PM which has many positive attractions to it. But the more research I have done, the less appropriate this PM approach seems to be for an active cyclist. As many on this forum have pointed out - cycling is not really facilitated by an accelerometer sensor, you need a "respiration" sensor as well. To my understanding, leadless PM's have only the accelerometer sensor. I would be very interested in hearing from other active cyclists and their experiences with PMs. Also, any who have also had AV node ablations. I know that even after the AV node ablation, my atria will still be fibrillating, but my ventricular contractions will be "normal" and regulated. But I still have concerns as to how the ventricles will be appropiately filled if still in afib.
Look forward to hearing from anyone with similar situation.
