afib [can you tell from SH?] - jerry1967 - 03-06-2018
Does anybody know what afib looks like on the flow rate chart or any chart of a sleepyhead program?

You will need some type of cardiac EKG or holter monitor to test for afib. Something like the Alivecor Kardia Mobile device. I have it and use it to test myself at least once a day. Last year I just got my APAP, using it for two weeks, and woke up with a crazy racing heart feeling in my chest. Went to the ER and was told I was in AFIB. It's a really weird sensation, hard to miss. Although apparently a lot of people don't feel it.

An xPAP can't tell what is going on with the heart. You could perhaps look at the respiratory rate if it increases during an episode.

I agree with Paula above. There may be a fairly tightly correlated breathing indicator when you are in full AFib, but maybe not, or it isn't a reliable and consistent indicator. The only way to establish if a certain breathing pattern accompanies AFib too frequently to ignore would be to have a Holter Monitor or similar device taking measurements for every hour you are on PAP. This would need to be done over several weeks to get enough data since I expect you don't go into AFib more than a few minutes at a time every other week or five...??
Fortunately, I don't seem to have had a recurrence of my own AFib after commencing a regimen of metoprolol. I still go for a 45 minute run two or three times a week, getting my heart up to about 150 bpm. It doesn't seem to bother my heart. Are you taking a blocker of some kind to keep the fibrillations in check? If so, it could be quite a lengthy period of monitoring before you can discern a pattern of breathing that accompanies the AFib.
Even so, I don't believe you will find a strong correlation between the two. During REM, yes, breathing most often changes, but I have no idea if REM and some types of dreams bring on AFib as well. Beta-adrenergic channel blockers, the beta blockers, are supposed to keep those under control in any event.
