If your sleep-time is when you enter AF, then it is 'Vagal' tone type AF, and not the more common 'adrenergic' kind. My SIL is like that. She begins to fibrillate shortly after her head hits the pillow, whereas mine would calm at that time. It's astounding, personally, how reliably I could count on my heart calming and letting me fall asleep. An hour earlier, not a hope. My heart would only fibrillate during the daytime when my mind was most active and involved.

You are a blessing to me! I so appreciate your encouraging reply! This morning, on another blog, I was reading a really great ‘good samaritan’ story. A true story that showed pictures, of an elderly man, like me, in the hospital. Passers by, had seen this man, either fall down, or lie down, on the sidewalk by the street, near a restaurant, in a city, here in the USA. They were concerned, and stopped their car. The driver got out, and rushed over to the elderly man, and could see that he was unconscious. So, he checked for a pulse, and could not find one. So, the good samaritan called out to his wife, in the car, to call 911, and tell them to get there pronto, because the elderly man had no pulse. Immediately, the good samaritan performed chest compressions, and gave CPR trained treatment to the elderly gentleman, and his wife checked for a pulse, until the ambulance arrived, with a defibrillator a few minutes later. The good samaritan saved this man’s life. He was revived! It turned out that the elderly man was having an A-Fib attack, and his heart stopped beating regularly, and he had just been released from hospital, where he had 2 previous A-fib attacks where his heart stopped, and they had to use the paddles ( defibrillator ), on him, both times, to get his heart back in sinus rhythm. The good samaritan was recognized for his life saving actions. Seeing this story, and knowing that I have no medicine or blood thinner treatment, of any kind, to protect me from having another A-fib episode, just made me all the more, anxious! So, ironically, years ago, when I was employed as a boss, over many hourly, union employees, in an internationally large manufacturing company, I had an employee, who fainted and I could feel no pulse, so, being trained in CPR, I started chest compressions, and yelled out, to another employee, to call the nurse and have her immediately come out, that I suspected cardiac arrest. The nurse came right away ( we had a medical station in our facility at that time ). She took over, and the ambulance came. I had saved that employees life. Because of the strong union though, he, nor anybody else thanked me for what I did, except the nurse. She was most appreciative! I’m just glad that I had CPR training! My daughter has a college degree in nursing, and my son-in-law is a hospitalist MD, so they can advise me, when I have issues that seem disconcerting, I reckon. Thanks again for your support. You have been the most supportive about A-fib, to me, than anyone else, and I deeply appreciate your words of experienced wisdom!!
