Does your medical system have something similar?
I'm not a professional pilot, but after I had a low speed motorcycle accident the FAA required for my Class 3 (private pilot) physical a full cardio workup (stress test, 24 hour ekg, ultrasound movie of my heart) because they were afraid the accident might have been caused by some kind of cardiac event.
I'm 61, bmi of 27.
Edited to add: I was upset about this at the time, but when I passed with flying colors I felt better about it. The heart doctor told me that the FAA stress test is the most 'stressful' one that he gives. He told me a lot of truck drivers come in for the same test, but their test isn't as 'stressful'.
