<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am 43, 230 lbs, 5 4 . I was just shocked about an hour ago. I have a heart condition POTS and the mild burn is just below my left breast. My bp is 122100, hr 90. My left arm and hand are going numb. Due to the location of the shock burnbeing so close to my heart and because of my POTS, do I have to go to the er?  <response>: Hi, I would recommend going to the ER for a physical exam, a resting ECG and cardiac enzymes in order to exclude possible coronary artery disease. POTS is not a life-threatening cardiac disease, but the chest pain could be related to coronary artery disease. An exercise cardiac stress test may be necessary if this situation persists. Hope I have answered your query. Let me know if I can assist you further.
