Had a similar, but perhaps not so severe, incident a year or so ago. EKG, stress test, carotid ultrasound, and CAT scan were clean. Been rowing, dragging dead animals, and working hard in the yard before and ever since, but it’s always kinda in the back of my mind. If it happens, I hope I’m having fun!
That stress test was my third. All concluded that I get tired and my heartbeat goes up when I’m driven like a mule by cardio techs. Duh!
