Cardiopulmonary Diagnostic Services


To determine the "state of your heart" and the condition of your cardiovascular system, our cardiologists and cardiopulmonary technologists may administer several kinds of diagnostic procedures. Some of the tests offered at RWJ Hamilton are described below.

An Electrocardiogram (EKG) records the electrical impulses traveling through the heart on graph paper. The purpose is to evaluate the heart's function, to determine the presence of abnormal electrical impulses and to detect heart damage.

Echocardiography (Echo) is a test that uses ultrasonic waves to form a graph or picture of types of tissue in the heart. The purpose is to learn about the heart's size, shape, function, movement and surrounding structures.

A Stress Test records the heart's electrical activity and performance under stress. This test is usually administered while the patient is walking or running on a treadmill.

Stress Echocardiography (Stress Echo) combines a stress test with Echocardiography, which utilizes ultrasonic waves to form a picture of the types of tissue in the heart.

A Thallium Stress Test combines a stress test with nuclear cardiac imaging. The patient receives an injection of thallium before the stress test, followed by nuclear imaging of the heart.

An Electroencephalography (EEG) is a non-invasive test that graphically records the electrical impulses of the brain cells.

A Pulmonary Function Test is a series of measurements that evaluate lung function.

Trans Esophageal Echo (TEE) is a test that provides visualization of the heart through a probe into the esophagus.

The Pacemaker clinic accurately and reliably records and transmits the patient's EKG and Pacemaker rate over the telephone.
