The correct answer would be stress tests. These are performed to assess the adequacy of the amount of oxygen getting to the heart muscle during exercise and at rest. With this, the absence or presence of a heart disease can be indicated. This is a common procedure done in Cardiography and Cardiovascular Monitoring Services. 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.
