Your Life-Threatening Risk of A-Fib with Untreated Sleep Apnea
At least 43% of patients with Atrial Fibrillation suffer from Obstructive Sleep Apnea (OSA) as well. In his A-Fib story, Kevin Sullivan, age 46, wrote about his discovering his Sleep Apnea on his own and the effect on his A-Fib. He wrote:
“My A-Fib seemed to start at night while I was sleeping. One night when I woke up, my heart was racing and I felt sweaty. I started reading about things which contribute to A-Fib and learned that high thyroid levels and sleep apnea contribute to the condition. My brother had sleep apnea, so that made me think I might as well.
When I asked my doctor about it, he told me that it was unlikely because I was not overweight and I did not feel tired during the day.
I went to a sleep lab anyway, and it turned out that I did have sleep apnea. My A-Fib was being triggered by apnea episodes during the night. I got an CPAP machine to address the sleep apnea and hoped that was the end of my A-Fib….“

Sleep Apnea is a common disorder in which you have one or more pauses in breathing or shallow breaths while you sleep. Breathing pauses can last from a few seconds to minutes. They may occur 30 times or more an hour. Typically, normal breathing then starts again, sometimes with a loud snort or choking sound.
Risk of A-Fib with Untreated Sleep Apnea
It is now established that there’s a connection between Sleep Apnea and A-Fib.
If you have untreated Sleep Apnea, you are at greater risk of having a more severe form of A-Fib or of not benefiting from an A-Fib treatment. To learn more about sleep studies, see my article: Sleep Apnea: Home Testing with WatchPAT Device and the Philips Respironics
More EPs are Sending Patients for Sleep Studies
So many A-Fib patients also suffer from sleep apnea that many Electrophysiologists (EPs) routinely send their patients for a sleep apnea study. Some A-Fib centers have their own sleep study program. (The patient just walks down the hall to an A-Fib sleep study area.)
For some lucky patients, normal sinus rhythm (NSR) can be restored just by controlling their sleep apnea and getting a good night’s sleep.
Take Action: Sleep Apnea Can be Lethal
Sleep apnea isn’t a minor health problem, and it’s a condition you can do something about. If your bed partner tells you that you have pauses in breathing or shallow breaths while you sleep, or that you snore, do something about it! (Not everyone with sleep apnea snores, but snoring may indicate sleep apnea.)
Talk with your doctors about testing for sleep apnea. You may need an in-lab or home sleep test).
