<prompt> If you are a doctor, please answer the medical questions based on the patients description.I was eating dinner, salmon to be exact, and while eating it my heart began to race and I felt dizzy and shakey. I havent been sick and it came on all the sudden. Does this have something to do with the salmon or something completely different  <response>: Hi, Allergy to cooked salmon finish fish is a possibility. Usually, such kind of reaction is associated with skin rashurticaria itching etc. Alternatively, it could be due to paroxysmal supra-ventricular tachycardia tachycardia may last for a few seconds or minutes i.e. self-terminate and consequent hypotension. 12 lead ECG with rhythm strip long lead II for 1 minute may throw some light. Hope I have answered your query. Let me know if I can assist you further.
