In hindsight, I am not sure what could have or would have been done differently to prevent the course of events that occurred in another state.  The intensity of his work-up was determined by his symptoms and he was symptom-free shortly after presenting to the emergency department.    It is interesting to note that both episodes occurred shortly after both doses of his Covid vaccination.  I am not sure of the causative link.
