Noninvasive Diagnostics

Additional diagnostics

The Heart Institute offers a full range of noninvasive services to diagnose coronary artery disease. Should you be scheduled for any of the following tests, your doctor will inform you of any pre-testing preparations.

ECG (Electrocardiogram)

Tracings, which represent the changes in electric potential produced by the contraction of the heart, are recorded using an electrocardiograph and evaluated by cardiologists. Service is available 24/7.

Echocardiography

Echocardiography is the utilization of ultrasound to generate images of the heart’s anatomy and function. During the test, structures, blood flow and valve function are measured and evaluated. Service is available 24/7.

Stress testing

Stress testing is a diagnostic modality utilized to evaluate the response of the myocardium to exercise. It involves a standard protocol of monitored Ambulation on a treadmill at prescribed speed and incline, or the injection of a medication, which produces a similar reaction in the heart as exercise. Reactions to stress are monitored through the use of electrocardiography.

Nuclear stress test

A nuclear stress test is a diagnostic modality involving the intravenous injection of a radioisotope, which serves as a marker to measure blood flow to the heart muscle at rest and during stress. It involves the use of a camera that aids in the tracking of the radioisotope. Stress may be in the form of exercise or may be pharmacologically induced. The test is performed in conjunction with the Nuclear Medicine division of the Radiology Department.
