Quizplus · Accepted Answer

The x-ray recording of blood vessels after the injection of radiopaque substance is called angiography. Electrophysiology refers to the study of the electrical activity in the heart, while a stress test is a test to evaluate the heart’s response to exercise. Cardiac enzymes refer to blood tests that measure enzymes released during a heart attack. None of these definitions match with a description of x-ray recording of blood vessels. Therefore, the best choice is C - angiography.
