DISCLAIMER: I’m not a medical skilled. Should you imagine you may have AFib or some other coronary heart/medical situation that wants consideration, please seek the advice of together with your private medical supplier.
Chances are you’ll be in nice form. Chances are you’ll be in nice well being. Chances are you’ll not have any heart-related points or exhibit any signs of coronary heart issues. However you could possibly nonetheless have AFib (atrial fibrillation) that’s an irregular heartbeat that might trigger a stroke. PEZ’s Chuck Peña takes you thru his private journey with AFib.
My AFib journey
Final summer season, I realized {that a} pal who’s a couple of years youthful than me (however each of us are formally “outdated”) and nonetheless a extremely aggressive age group triathlete had a coronary heart episode whereas at a hospital (he was there for one more not coronary heart associated motive, so each ironic and fortunate for him) that required speedy emergency care. He was recognized with AFib (atrial fibrillation), which is a sort of arrhythmia or irregular heartbeat.
Though I’m in good bodily situation and was not experiencing something uncommon with my coronary heart (the commonest symptom of AFib is palpitations, a quick, fluttering, or pounding heartbeat), I believed if one thing like that might occur to my pal who’s youthful and in higher form than me, it might in all probability be a sensible concept to get myself checked out.
So I made an appointment to go to a heart specialist. They took an electrocardiogram (EKG or ECG) that information {the electrical} indicators of your coronary heart, which didn’t present something significantly uncommon. However per week later, I used to be sporting a Zio distant coronary heart fee monitor, a small, discreet, snug patch utilized to my chest to watch my coronary heart rhythm throughout regular day-to-day exercise, together with whereas I slept, showered, and exercised — recording each single heartbeat for evaluation over the subsequent two weeks. One in every of my rides throughout that two week interval was a semi-epic journey that included Bare Mountain and Mount Climate (each climbs are rated Cat 3 by Strava), which is a reverse model of what’s generally referred to as the “Blue Ridger” right here in Babylon on the Potomac the place the climbs are literally tougher ridden in the other way — 57 miles and 4,700 toes of climbing.
Shortly after sending my Zio HRM again for evaluation, I had a coronary heart ultrasound (echocardiogram) that produces shifting photos of your coronary heart to indicate how your coronary heart and valves are working. The tech mentioned I used to be in all probability probably the most match particular person ever to return into the workplace for testing. And it seems that his dad (a health care provider) was a comparatively latest convert to biking so we ended up having an ideal dialog concerning the sport.
About two weeks later I had a telehealth name with a tech. The excellent news was that the echocardiogram didn’t present any proof of coronary heart illness. However the tech knowledgeable me that the evaluation of my Zio HRM confirmed AFib. The speedy concern was that AFib will increase the chance of blood clots within the coronary heart that may journey into the bloodstream and into the mind, resulting in a stroke. So I turned the latest poster boy for Eliquis, a blood thinner that helps stop blood clots.
A few week after that, I had what’s referred to as a “nuclear stress check” that makes use of a small quantity of radioactive materials, referred to as a tracer or radiotracer, to indicate how blood flows to the guts at relaxation and through train. They knew I used to be an energetic athlete so not a “typical” affected person. It took loads longer than regular and the treadmill was shifting quicker (however I wasn’t operating — they really need you to stroll and it’s a must to maintain onto a bar whereas doing so … not precisely the simplest factor to do if you’re attempting to go “quick” and elevate your coronary heart fee) and at a steeper incline than for many different sufferers to get my coronary heart fee excessive sufficient (which was a lot larger than what they might usually go for a “regular” affected person) for the train portion. Apparently, my coronary heart went into AFib throughout the check, which the tech identified to me on the monitor.

The follow-up was excellent news: good blood circulate and no blockage, i.e., wholesome arteries and never in danger for a coronary heart assault.
AFib and sleep apnea
One of many “attention-grabbing” issues concerning the evaluation of sporting the Zio HRM was that I had some unusually lengthy pauses between heartbeats once I was asleep. So I used to be referred to a sleep specialist and did an in a single day at-home sleep check. The check consequence was that I had delicate sleep apnea (principally occurring once I was asleep on my again however not on my aspect).
It seems that there are some robust relationships between AFib and sleep apnea. In response to the Cleveland Clinic:
The prevalence of sleep apnea is exceedingly excessive in sufferers with atrial fibrillation — 50% to 80% in contrast with 30% to 60% in respective management teams. Conversely, atrial fibrillation is extra prevalent in these with sleep-disordered respiratory than in these with out (4.8% vs. 0.9%).
However based mostly on the outcomes of my sleep check, my heart specialist didn’t assume my sleep apnea was a trigger/issue for my AFib.
Apple Watch and AFib
If in case you have an Apple Watch 4 or later or an Apple Watch SE (what I’ve), you should use AFib Historical past in your Apple Watch to estimate how incessantly your coronary heart is in arrhythmia.
Alternatively, you possibly can set your Apple Watch to allow irregular rhythm notifications that is perhaps suggestive of AFib (what I’ve carried out). Right here’s what Apple says about efficiency of the irregular rhythm notification characteristic:
Enrolled topics wore an Apple Watch and a reference electrocardiogram (ECG) patch concurrently for as much as 13 days. For these topics contributing information to the major endpoint evaluation, 32.4% (n=140/432) offered with AF as recognized on the reference ECG patch and have been included in figuring out the machine sensitivity. Of these, 124 acquired an IRNF (irregular rhythm notification) with concordant AF on the ECG patch, and the sensitivity was 88.6%. Of the 292 topics who didn’t current with AF on the ECG patch and contributed information to the evaluation of machine specificity, 290 didn’t obtain a notification. The AF detection specificity was 99.3%. The remaining topics (n=141/573) both contributed information to solely secondary endpoint analyses and/or didn’t full the examine. These outcomes help the machine’s effectiveness in detecting AF.
Nearly all my irregular rhythm notifications have occurred throughout sleeping hours. I’ve solely had a couple of once I’m awake. And none throughout train.
Driving with AFib
Throughout this entire time, I used to be using my bike no in another way than I usually would. That means: 100+ miles per week; most weekday rides solo and straightforward/average (apart from my Wednesday Night time Hill Journey aka WNHR aka Peña Peña aka Ache Social gathering); tougher and longer rides on the weekends (however I’m now not racing or coaching for something so my using is simply using). No matter my using, I didn’t obtain an AFib notification whereas using. I interpret that as “good” (however bear in mind … I’m not a medical skilled).
However I do imagine AFib may clarify a few of my “off” days during the last couple of years. I’ve had a lot of days (typically strings of days) once I simply couldn’t go as laborious as I wished (and may have in any other case been in a position to) — particularly on climbs, my favourite terrain. I didn’t have a proof for it (apart from being outdated and sluggish) — I hadn’t been sick, I wasn’t in any other case drained, and it wasn’t like I hadn’t been using. I believed possibly I used to be experiencing the after results of getting asymptomatic COVID-19 that I used to be unaware of (NOTE: throughout that point, I used to be by no means examined for COVID-19).
Once more, I’m not a medical skilled and this can be a single anecdotal information level, however …
- My Apple Watch notified me of a number of AFib detections within the early morning hours on a Friday.
- That Saturday once I rode, I went comparatively straightforward however my coronary heart fee was excessive for the extent of effort.
- That Sunday once I rode, I “plateau’ed” when it comes to energy output, i.e., I simply couldn’t go any tougher on sections the place I’d usually be capable of, and my coronary heart fee wasn’t elevated for the extent of effort.
I wasn’t in AFib throughout the rides (in line with my Apple Watch), however I surmised I used to be feeling the lingering results of AFib. FWIW, my heart specialist and one other coronary heart specialist each subsequently instructed me my “analysis” was in all probability proper.
AFib and endurance athletes
The place would we be with out Google? Should you do a Google search on “afib and endurance athletes,” you’ll discover a plethora of analysis. Listed below are only a few issues I discovered:
- There may be proof for a better prevalence of AFib in athletes engaged in long-term endurance sports activities coaching in contrast with the final inhabitants.
- Endurance train coaching produces a number of cardiac diversifications together with adjustments in electrophysiological perform which will make endurance-trained athletes extra weak to AFib.
- A fancy relationship exists between train and AFib. Average train reduces AFib threat whereas intense strenuous train has been proven to extend AFib burden. It stays unclear at which level train could develop into detrimental.
And for all of the MAMILs on the market:
- AFib is the commonest arrhythmia in middle-aged athletes. Bodily train carried out in an everyday foundation has been proven to be useful for cardiovascular well being. Average bodily train, except for producing a pleasant, peaceable and well-being sensation, has been related to a decreased threat of AFib. Nevertheless, extra strenuous endurance train, just like the one experiencing marathon runners, appears to extend the chance of AFib in wholesome athletes with out natural coronary heart illness.
- Whereas the prevalence of AFib is low in younger aggressive athletes, it will increase considerably within the getting old athlete, which is presumably related to an accumulation of lifetime coaching hours and participation in competitions. A latest meta-analysis revealed a 5-fold elevated threat of AFib in middle-aged endurance athletes with a placing male predominance.
- Rising proof signifies that power high-intensity endurance train predisposes male, middle-aged athletes to elevated threat of AFib.
It is a little dated (2016), however right here’s an article about 9 world class athletes residing with AFib, certainly one of whom is former professional bicycle owner Haimar Zubeldia, who twice completed fifth total within the TdF (’03, ’07).
My heart specialist’s suggestions
After about 4 months of residing (and using) with AFib and “managing” it with Eliquis, my heart specialist and I mentioned my choices going ahead.
One possibility was to easily preserve doing what I had been doing. In a single respect, it was working, i.e., my threat of a blood clot from AFib was decrease and I wasn’t any worse off. However for me, this was not a most well-liked possibility (if there have been different decisions) as a result of (a) I didn’t need to must be on a drugs, i.e., Eliquis, and (b) based mostly on my analysis (that my heart specialist confirmed), my AFib would possible solely worsen (the share of time my coronary heart can be in AFib would enhance) over time. It additionally meant that AFib would proceed to have an effect on my using (and life).
Another choice was a Watchman implant — a tool that closes off the left atrial appendage to cut back the possibility of stroke by stopping blood clots from coming into the bloodstream. This was a sexy different to blood thinners. Nevertheless it in all probability nonetheless meant that AFib would proceed to have an effect on my using. In different phrases, like Eliquis, a Watchman would tackle the consequence (positively a great factor!) however not the foundation trigger.
A 3rd possibility was catheter ablation, which makes use of small burns or freezes to trigger some scarring on the within of the guts to assist break up the defective electrical indicators that trigger irregular heartbeats and restore a typical heartbeat. My heart specialist thought I’d be a great candidate for this process as a result of:
- My AFib was nonetheless in a comparatively early stage (the Zio HRM evaluation confirmed my coronary heart to be in AFib about 15 % of the time)
- My coronary heart was in any other case wholesome with no different points
- I used to be in superb bodily situation and well being
Assuming a profitable process (the general success fee for catheter ablation is about 75% and if a second process is required, the success fee will increase to almost 90%), my heart specialist mentioned I’d basically be carried out with AFib, i.e., my heartbeat must be restored to regular. Clearly, this seemed like the absolute best end result so I scheduled a seek the advice of with an electrophysiologist (a heart specialist who focuses on testing for and treating issues involving irregular coronary heart rhythms).
I had a lot the identical dialogue with the electrophysiologist that I had with my heart specialist. One factor I’m grateful for is that each of them understood and appreciated that I wasn’t a “regular” affected person, i.e., my degree of train was effectively past that of different sufferers who “exercised recurrently.” So their diagnoses and suggestions weren’t simply “customary” responses extra relevant to the sorts of sufferers they recurrently encounter and so they took under consideration the truth that I’m an athlete.
As this goes to press, I’m scheduled for a catheter ablation in early March. I’ll be having it carried out at a hospital with top-of-the-line cardiac electrophysiology applications and workers within the nation. And my surgeon would be the chief of advanced ablation. So in good palms. Hopefully all of it goes effectively and I might be AFib-free afterwards. I’ll preserve y’all posted!
Some parting ideas
Though you could be in good/nice form and never experiencing any coronary heart points/signs, my expertise would say that it nonetheless is perhaps a good suggestion to get your self checked.
- Estimates of the prevalence of AFib in america ranges from about 2.7 million to six.1 million. That quantity is estimated to rise to 12.1 million in 2030.
- One evaluation exhibits a excessive prevalence of undiagnosed AFib in america, i.e., folks like me who’ve AFib however don’t understand it as a result of they’re in any other case in good condition, wholesome, and never experiencing any signs
- Worldwide, the estimated variety of people with AFib in 2010 was 33.5 million, in line with a 2013 examine. That’s about 0.5 % of the world’s inhabitants.
- AFib will increase the chance of stroke by fivefold and practically 35 % of individuals with AFib could have a stroke.
If you wish to be taught extra about coronary heart circumstances (together with AFib) in athletes, The Haywire Coronary heart by Christopher Case, Dr. John Mandrola, and Lennard Zinn is a should learn.
Three essential takeaways for me from the e-book:
- One warning signal that you simply might need AFib is
Persistently low energy: A lower in sustainable energy is the actual warning signal right here. There are many causes for low energy output, together with pure variability, overtraining, and medical circumstances. Normally it’s the primary two. But when your sustainable energy drops, take notice.
Looking back, I imagine I used to be experiencing this.
- Primarily based on a examine with greater than 1.2 million individuals
average caffeine consumption (3 to five cups per day) related to a decrease threat for coronary heart assault, stroke, or demise associated to coronary heart illness. Sure, decrease … Medical doctors ask sufferers with arrhythmia to surrender loads: alcohol, coaching, tense conditions, and extra. It’s good that athletes can get pleasure from an espresso with out guilt.
Even earlier than I learn the e-book, I instructed my heart specialist that I wasn’t giving up espresso stops on rides
- By far, the primary (authorized) irritant to the guts is alcohol … the connection of alcohol to arrhythmia is linear. That means: One drink per day results in a small threat of AF; two drinks double the chance; three drinks triple the chance; and so forth. I haven’t given up Negronis, wonderful wine, or good beer, however now understanding that decreasing alcohol consumption could cut back the burden of arrhythmia, I’m being higher about my consuming, e.g., attempting to not drink throughout the week and solely a few drinks on weekends.
All I do know is that I contemplate myself fortunate to have found my AFib (which I in all probability had for some time, however simply didn’t understand it) once I did. And that I’ve been in a position to be proactive and do one thing about it. Not less than I’m giving myself each alternative to stay as much as the adage of my favourite rider/racer, Fausto Coppi aka il campionissimo …
