question: Today my heart slowed way down it almost felt like I was short of breath and there was pressure on my chest. I felt like everything was in slow motion really weird feeling. This is the third time this has happened to me in 1 year . The first time felt like it lasted so long like 8 sec these last two times were just a few seconds long. I am 22 years old 5'8" and weigh 125lbs I would say I'm healthy I work out at least 3 times week. I've had doctors listen to my heart but they don't detect anything wrong well because this doesn't happen all the time just randomly. every single time has been when I'm just relaxed not stressed no anxiety I don't understand please help!
