"Glad I found this thread, I know its old. I just wanted to give my experience. I am 64 and by no means an endurance cyclist. Last summer I was doing 2-3 rides a week totaling 35-40 miles. Mostly up and down RT-1A in New Hampshire so very few hills. I suddenly started having bouts of excessive heart rate lasting 30-40 minutes not necessarily tied to cycling. Mostly just puttering around the cottage. In fact it only happened twice while on the bike. I contacted my PCP back in Texas and he recommended getting to urgent care when it was happening because it might be A-Fib.
I ended up getting a Kardia device and next time it happened sure enough it was A-Fib. I went to urgent care the next time and of course A-Fib was over by the time I got there. They ended up sending me to the emergency room where they kept me on an EKG for about 2 hours without further arrhythmias. I told them both at urgent care and ER about the Kardia mobile report. Nurse at urgent care was interested but never heard of the device, ER doctor downplayed the device as a toy. ER referred me to a Cardiologist in Maine. The cardiologist said that the Kardia device did a good job of diagnosing A-Fib but of course was not as accurate as the machine. She put me on metoprolol to take as needed to control heart rate, put me on a Zio monitor for two weeks and requested a echocardiogram which I did back in Texas because of time constraints.
Oddly the heart events ended as fast as they started and the Zio monitor picked up no events where I had about 30 events in the previous 6 weeks. No events September- December. Early January I had an A-Fib event and this time it lasted about 6 hours instead of 30 min. I saw my PCP and he put in a note for a cardiologist to contact me. The next day while loafing around the yard my heart rate started climbing into the 140s and would not go down BP got up to 176/115 and I ended up going to the ER (ER doctor never heard of the Kardia device). No A-Fib just rapid heart rate and high BP. Finally saw the Cardiologist/ electrophysiologist in Texas (who also was a fan of the Kardia device) then had catheter ablation surgery the first week of Feb. Since then no events knock on wood. The ablation surgery really threw me for a loop. For some reason I was expecting the recovery to be about like that of a colonoscopy...I was wrong.
Prior to the surgery I was not really doing any riding but was spending 15 min every day on my trainer doing moderate cardio. After the surgery I was reduced to just puttering around the house in my PJs for a few days and had a strange craving for my Grand daughter's Peanut Butter Capt'n Crunch. After a week I got back on the trainer and tried in an easier gear but was back off after less than a minute. I kept going at it and now after a month I can do 10 minutes of reasonably hard cardio. I am currently on Eliquis for about another 3 weeks and scheduled to wear a Holtor monitor for two weeks starting next Friday. After that who knows...? Hoping I get completely back to normal by May because I really enjoy my rides up and down the beach."
Thanks for posting.- I was diagnosed with afib a couple of years ago when I fell backwards on an icy sidewalk and had concussion and brain bleed. I'm on 200 mg of amiodorone a day and also eliquis. Had hip surgery 16 months ago and now trying to get back in shape. I am worried about pushing myself in rides greater than 20 miles. Used to love group rides but would now hate to keel over and spoil for others. Will be 77 this November. I wear a health watch and try to keep heart rate below 140 bpm
