Answers:    they'll tender you a small dose of thallium and conduct a stress test. For some relations its safer than the treadmill stress test. Don't be afraid, its not fruitless. Just remember to breathe. You'll sail through it, travel home, and pee funny colors.

they are simply doing a stress test and i assume you cannot run on a treadmill so they will stress your heart chemically instead it is protected and controlled you will be fine
