[|Human|] im 26 have pains that come and go in my left shoulder. i suffer with palpitations but am not having any at present or with the pain. the pain in shoulder doesnt happen if i move it comes on its own. could it be cardiac? it can shoot in my shoulder and it can be very sharp and painful
[|AI|]  Hi, Cardiac pain is exertional and occur during exercise or exertion. It is diffused in nature and can not be localized. Therefore, the Pain you are having seems unlikely to be of cardiac origin. Palpitations can be cardiac related. I'll advise you to get an ECG done at the time of these palpitations and a 2D Echo to rule out any possible cardiac related abnormality. Cardiac arrest means stoppage of heart and a person with cardiac arrest does not write a question by himself. Hope I have answered your query. Let me know if I can assist you further.
