<s>[INST] Hi I am a 21 year old female, 112 lbs. Well I've been  having shortness of breath and a high resting pulse of 126, and sometimes chest pain and heart spasms(according to a nurse).....Anyway my pulse seems really fast alot without much to any activity.like when I went to bed, I got sharp chest pain and my pulse increased more for a few seconds....is this anything to be concerned about? [/INST] The presentation you are referring to is more of a anxiety symptom complex rather than typical chest pain of any cardiac pathology. Reduce stress, drink lot of water. Take Tab. Xanax 0.25mg one at night for 3 days. </s>
