I have also been diagnosed with Paroxysmal AFib. My symptoms almost always occur at night as I am falling asleep or when I am sleeping (it wakes me up). Big meals are also a trigger. When an episode occurs, I stand up and will do jumping jacks or run in place for up to a minute and then repeat after a few minutes. It will return to NSR within minutes to 45 minutes. I can sometimes return to NSR with breathing exercises. I am an otherwise healthy 60 year old runner who stays in really good shape without any other contributing factors. Since being diagnosed, I have stopped drinking alcohol and caffeinated beverages. Sleeping on my left side is a trigger. I take Magnesium Glycinate, COQ10, and D3/K2 supplements. I have seen two EPs. Only one was willing to consider the Vagal Nerve as being a contributing factor. When I explain what I am doing when I have an episode, they brush it off as being coincidental. I have ordered a TENS unit and will report back if there is improvement. I am convinced that my AFib is caused by the Vagus Nerve and I am hoping to treat it without having an ablation. I would really appreciate hearing from others on this topic.
