Is my heart okay?

[Flech]

I am a 22year old male who had foolishly taken ecstasy, which didnt quite bring me tachycardia but and elevated heart rate that i went to the emergency room. I was released after my ekg came back normal, however since the event ive had chest pains and shortness of breath. Ive since gone to my primary doctor twice more and had two more ekgs performed, all normal from the doctors interpretation. He attributed it to have anxiety and has since prescribed me on xanax, however im still concerned that maybe something was missed because i still occassionally get chest pain and shortness of breath, and ive never had a heart condition before. Should i go see a specialists? or am i just worry myself into more pain because of the anxiety.....please help! :(

You may have a cardiomyopathy, and it may not be connected with the ecstasy you took. I would suggest an echocardiogram to make sure all of your heart's functions are acceptable, such as the valves and heart walls. In addition there may be some lung issues, such as asthma that you may be missing, so a respiratory evaluation such as spirometry may be helpful as well.
