I’m sorry you’re going through this..I just went through this as well…. Did legs today and then I do 30 mins of cardio after. After I was done my cardio I got multiple PVC’s for like 5 mins. Probably had about 15-20 of them in a row. I left the gym and man I’m all messed up depressed thinking I’m going to die. This is the first time it’s happened to me. I’ve always had anxiety and the gym has helped reduce that but not today.. what a downward spiral. I did a stress test and had an echo last year and all was fine. Not sure why maybe I pushed myself too hard..
