I saw my cardiologist - it looks like we don't need to do anything special because I'm not experiencing any serious symptoms. My cardiologist did want to send me for a heart ultrasound, just as a precaution. Unfortunately, he has decided he doesn't want to accept my VA insurance - so the VA will be sending me to a different cardiologist. I've been on a Bipap for a couple of years - and there is a connection between sleep apnea and afib., and my AHI numbers have been pretty high recently, so I'd like to have another sleep study done to see if they can determine if the sleep apnea is causing/affecting my afib, and/or if the afib is causing/affecting the rise in the number of times I stop breathing (AHI number) during the night.
