<human>: 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
<bot>: Hi, Allergy to cooked salmon (finish) fish is a possibility. Usually, such kind of reaction is associated with skin rash/urticaria & 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.
