Cardiovascular Diagnostic Testing

Screenings and advanced diagnostic tests provide important insights about the heart and blood vessels. Physicians at Central DuPage Hospital use sophisticated technologies to provide comprehensive detail about the structure and function of the heart and blood vessels. We provide diagnostics for adults and children.

        What is a Stress Test?

        A stress test is a non-invasive test that helps the physician identify how well your heart works during exercise or exertion. During this test, you may walk or run on a treadmill while monitors measure how hard your blood is pumping.

        For a nuclear stress test, you would be injected with a mildly radioactive substance before doing the stress test. This helps the doctor see how blood is flowing during exercise. The radioactive substance is excreted from the body within 24-48 hours.

        What is Echocardiography?

        A non-invasive test that uses sound waves to produce a study of the motion of the heart's chambers and valves. The echo sound waves create an image on the monitor as an ultrasound transducer is passed over the heart.

        What is Electrocardiogram?

        An electrocardiogram (EKG or ECG) monitors the heart’s electrical function and rhythm during normal activity.

        What is Holter Monitor?

        A Holter monitor is an ECG recording done over a period of 24 or more hours. Three electrodes are attached to the patient's chest and connected to a small portable ECG recorder by lead wires.

        What is an Angiogram?

        An angiogram (also called arteriogram) is a special X-ray of the heart and arteries. It is used to identify blockages and damage in the heart and blood vessels. For this test, you would be injected with a special dye that the X-ray can detect. The dye may be injected via a very small tube (catheter) that is inserted through the groin or arm.
