bipap causing atrial fibrillation

my doc took me off my bipap. everytime i use it my heart goes into atrial fibrillation. my pressure is 4/8. my ahi is less than 1. if i dont use it i feel great. not tired, no problems. use it and i am exhausted and wake up in atrial fib. anyone have any idea what could be happening?

I'm not a doctor, but my quick look of the info on line would suggest there should be a benefit in treating OSA when you have atrial fribillation. Is this a recommendation of your sleep doctor or your cardiologist. The article at the link below suggest both conditions need to be treated.

Sleep Apnea and Atrial Fibrillation: How They’re Connected

After I started CPAP last year, I was on it for two weeks. Then I had an AFIB episode, and immediately put on Multaq for AFIB. I figured it was because of years of untreated sleep apnea. Before starting CPAP, I was waking up with a lot of tachycardia problems. Since now on BIPAP, I had only one other episode of Ventricular Bigeminy and that was due to a LOT of obstructions all-in-a-row during one night.

I don't see how BIPAP could cause AFIB, unless you are still having obstructions. Have you downloaded sleepyhead software to look at what it shows? Even with AHI < 1, it could still show flow limitations.

i did not have afib before i started bipap. i ONLY have it when i use bipap. with bipap my ahi is below 1. i do have sleepy head but i dont know what to look for as far as flow limitations. my ahi without bipap is 15.

Why do you have a BiPAP and and not a CPAP? At an IPAP of 8 and an EPAP of 4 it's doing almost nothing that a CPAP of 4 wouldn't do, apart from slightly increase your chance of leaks.
