A couple years back, I was in hospital for minor surgery and a major infection. I got a text in the middle of the night from DW that she was in a-fib. I called and didn't get an answer. I checked the "Find My Friend" feature and saw her blip barreling down the Highway towards me, 20 miles away, and I knew damned well she wasn't the one driving and there was only one possible destination.
Atrial fibrillation is not inherently dangerous, but when DW gets it, she gets confused and panicky and feels like she's going to die. If I'm there, I take care of making sure she takes the right pill and stays calm, and she generally cardioverts in an hour or two. But with me in hospital, she didn't know what to do, so she did the best thing under the circumstances and called 911. They came right over, and because it was heart-related, took her to the closest hospital.
Meanwhile, I had called a nurse, had my IV drip attached to a wheelchair and had myself wheeled down to the ER to meet her.
