Do you monitor your intensity as in keep it low?
Nope! Iāve gone up to max HR a few times now, the only thing the cardiologist and I agreed on was no more time trialling, ie no more flat out 20-60min max HR stuff!
In fact here is a link to research saying HITT training is good for A Fibā¦
Backgroundā
Exercise training is an effective treatment for important atrial fibrillation (AF) comorbidities. However, a high level of endurance exercise is associated with an increased AF prevalence.

Soā¦it happened again:
2hr @ 72% FTPā¦113 HRav.
Spike during cool down, from 85-165 ~50sec.
Weird. This has never happened before and now itās the third one in a month, and only during warm-up or cool down.
Have an appt with a heart doc in a few weeks, will be sure to mention it w/ visual aids.

Can you try a different HR strap? There is a handy tool that I got off amazon called Kardia. Itās not cheap but it could give you an ECG reading when you are having those episodes which may help narrow it down and eliminate HR strap issues??
Do you feel anything when itās happening?
Not a thing; totally asymptomatic. Also completely asymptomatic during my other heart thing (hypertensive reaction to exerciseā¦thus far).
However, over the past year, since Day 1 after the bad news appt w/ the doc, Iāve been super hyper-focused on my heart and developed psychosomatic chest āachesāā¦as in every little thing she does is a heart attack and/or stroke. 
Iāll ask the doc about it, if recording that info is worth it for me. In my conservative bias, seems a bit sketchy to measure an ECG from just 4 fingers vs 12 whole-body electrodes! Back in my dayā¦

The way the Kardia works is that it takes an initial reading that is sent to one of their medical professionals for evaluation. Then all the functions of the device are unlocked for use.
The advantage of the Kardia is that you can always have the device with youā¦so if you have intermittent A-Fib and you feel things like a flutter in your chest, etc. you can grab your phone and hopefully take a reading while it is occurring.
As noted above, A-Fib can only be diagnosed by your doctor, but having readings when symptoms / incidents occur can significantly help your doc evaluate the situation.

I absolutely did the same thing during my āepisodesā I felt like I couldnt relax, and I hated every minut e of it.
Good luck man.
Thatās not how it worked for me, I never sent any reading anywhere and it all worked 100% āout of the boxā, with ECGs, diagnosis etc. In my limited testing the Apple Watch 5 appears to be as good as the Kardia.
Interestingā¦their original 510(K) clearance from the FDA limited the scope under which they could market / utilize their A-Fib feature. A medical professional had to review a reading before the full features of the device could be unlocked.
Iāll have to check and see what their 510(K) calls for nowā¦
I would concur with that in my case. One of my a-fib episodes last year happened when I was with a friend who had the latest gen Apple watch. I told him I knew I was in a-fib and he slapped the watch on me. Within just a few seconds it turned red and said āyou are experiencing symptoms of a-fib. Seek medical attention immediatelyā.

Yes, that is a big difference. I donāt know the exact regulations in the UK, but I know we can market and sell our A-Fib blood pressure monitor there.
donāt know - but I will be asking my cardiologist who I catch up with every 6 months. Will advise
Hello, I havenāt got to the end of this thread yet but before I forget to ask do you mind telling us the name of this product?
Thanks.
A very interesting thread this, it seems that heart conditions are more common than I ever imagined. Last week I had 3 or 4 days of episodes of rapid "vibrations " for want of a better word but they just went away a few days ago. Through this time my heart rate remained stable, I checked it on my phone while this feeling was present and saw no change. Iāve recently started the 531 weight training app and had done some bench presses so tbh I put it down to a twitchy chest muscle. I wear a HRM on every ride and havenāt noticed anything untoward although I did have a few days off and then just did 3 days off low effort rides just in case.
What amazes me in all this is that doctors say itās OK to continue training even when your heart rate is going crazy, what an amazing organ your heart it.
Very interesting thread and thanks to all of you who have described your symptoms etc.

Is anyone else working around afib while training consistently? Iāve been dealing with an increasingly intrusive heart arrhythmia that was diagnosed as ābenign heart palpitationsā. Was never able to get it captured on an EKG or Holter monitor. About two hours into a three hour ride on Sunday, I got hit with another bout. Usually they last about an hour or so, but this one was a sustained episode and lasted all night and into the next day. By an incredible stroke of luck, I had a cardiology appointment the next morning, and was still arrhythmic when I checked in for my appointment. They took an EKG, diagnosed the issue as afib, and prescribed a medication (calcium-channel blocker) used to treat high blood pressure. Within 9 minutes of taking the first pill my heart rhythm went from total chaos to rock solid. I was concerned about executing workouts on this medication since one of the effects is to lower oneās heart rate, but the last couple of workouts Iāve had no noticeable effect other than -5 or -10 bpm. Anyone else successfully treating afib with meds? If so, howās it impact your training?
