Hi all, so I've been getting sharp chest pains maybe once a weeks for a few months now shortness of breath and a couple of borderline ecgs, I'm currently on a 24 hour heart monitor my heart rate completely rested is around 88-100 slight movements 100-110 and walking or going up the stairs shoots up to 125-150 I'm 23 years old, slim built, is this normal or considered a tachycardic heart rate? My results will take a while to come back in trying to see if I'm overanalysing or if this is going to be a potential problem, thankyou
