22/Male. At age 16, noticed fast heart rate, not palpations (but i get those) anyway went through all the tests, ekg, echo, stress, all came back normal. I do sometimes get palpations, like if i bend down to pick somthing up and move up really fast, or once at work picked up a box and turned quickly with it and it triggered palps. Ususually don't last too long, maybe a minute or 2. I can usually stop them by holding my breath, when they stop my heart rate still seems fast but it's not bouncing out of my chest. I also sometimes get the feeling in me that it's about to start but doesnt. I suffer from Pectus Excavatum (depressed sternum) and anxiety.
Just wondering if anyone can relate to this.
