Cyclist’s Account of Atrial Fibrillation

I came across this blog entry from John Mandola, MD, a cardiologist who is also an avid cyclist. He describes his experience with an episode of atrial fibrillation (AF), an irregular heartbeat that originates in the upper chambers of the heart.

We’ve talked about this problem previously here at the blog, but I thought that this cyclist’s personal account would hit home about how the patient feels.

The account could also provide some reassurance that, sometimes, AF terminates quickly, a normal heart rhythm is restored, and no further treatment is needed. But it’s important to note from the account that the cyclist took the symptoms seriously, went to see the doctor quickly, and was evaluated thoroughly. A good example to follow.

    Hello Dr C,

    Thanks for posting such clear and detailed information on your blog. I am just starting to move from marathons to triathlons and have had an irregular heartbeat a few times that lasted several minutes each time. The information that you provide has encouraged me to take this more seriously and work with my doctor to make sure I am training in a safe way.

    Here is to more races and good heart health for us all. Thanks and keep up the great work.

    Thanks for your kind comment. It sounds like you’re on the right track. It’s easy for “healthy” endurance athletes to underestimate the importance of heart-related warning signs.

    And good luck with triathlon. Have a great season.
