Even half-milligram weekly doses seem to set off AFib from tiny triggers like tomato sauce or eating close to bedtime. Those things never caused issues before I restarted small amounts after stopping for back pain tied to the gallbladder. Not claiming cause and effect, but it lines up oddly. This reading came at five in the morning after spaghetti and meatballs with sauce the previous evening. Two hundred milligrams of the usual med brought it down after a couple hours.
62M, former athlete. Holding steady around 192 pounds, down from 262. Still strong and able to move slowly despite several autoimmune conditions that originally triggered AFIB thirty years ago. No episodes since then until recently. While working on the moving truck I fell about six feet from the cab. Building a platform for the puppy, I missed the step, hit a tree with my headphones, then the truck, then the ground. Got banged up but the multiple impacts kept me from breaking anything. Heart jumped straight to 160 and stayed there. I stayed on the ground half an hour trying to calm it. Watch showed AFIB with a high rate that slowly dropped. Next night, a little over twenty-four hours later, it went back to steady sinus rhythm in a hot shower with that sudden relief feeling. No trouble since. The adrenaline from the fall clearly drove the rate up. Haven't had any AFIB since then.
