After posting numerous comments on this forum discussing my success at avoiding Afib through controlling gas buildup, I feel that it is important to be candid about any setbacks. This past Saturday, I was awakened at 4:30 AM with Afib and remained in arrhythmia for 8 hours.
I waited it out and have been fine since then. The trigger was pretty clearly sleep apnea, perhaps exacerbated by some stomach-gas discomfort. After getting up for the bathroom a few hours before the Afib episode, I lay back down for a moment on my back with head and shoulders elevated and fell asleep before I remembered to assume my side-sleeping, chin-up sleep-apnea-avoidance position. I tried to suppress the onset with deep inhalations through my nose and relaxed inhalations from my mouth, but the triggering was too firmly in place by the time I woke up.
This was the 2nd event over the past 9 1/2 months, so I hope it is an isolated one, and that I can continue to avoid Afib by monitoring my diet, relieving gas and sleeping in the right position.
I still believe firmly that some of us can improve our Afib avoidance by dealing with these two triggers. I know that is not applicable to many sufferers.
