Chest pain, tightness, and a high heart rate?
I have been to the doctors for this but all of the tests came back fine. I was told i have an arrythmia but that it is no big deal.This has been happening on&off for a year. My chest has sudden sharp pains & my chest feels tight, like it’s difficult to breathe. My heart rate escalates, too. The last couple days, my resting rate was 90-120 bpm. I am not anxious or stressed. I’m a 19 y/o female, otherwise healthy. Not sure if I should get it checked out again, since all of the tests came back fine. What could it be? Thanks!
