During this test, the patient is asked to do exercises usually using a treadmill while the patient is hooked on an EKG or electrocardiogram machine. As one exercises, the doctor would monitor the heart rate reading the systole and the diastole. There are also imaging tests to be able to capture pictures of the blood flow in the heart.
