Impedance Cardiography

What is Impedance Cardiography (ICG)?

An impedance cardiography is a noninvasive test that measures the mechanical function of the heart.  This test provides information for your physician about your heart's ability to pump blood throughout the rest of the body, how forceful each heartbeat is, and the amount of fluid in the chest.  Since this test is noninvasive, it can be done in your doctor's office or in a hospital.

An ICG test is usually used on patients with congestive heart failure (CHF), high blood pressure, lung disease and other cardiac conditions.  This test may provide helpful information to help your physician better assess the severity of CHF, adjust medications, and determine whether or not a patient may need further testing.

How is an ICG performed? 

An ICG is performed similarly to an EKG.  Four electrodes are placed on each side of the patient's neck and chest.  Cables are connected to each electrode which are directly linked to the ICG monitor.  Information about the patient is entered directly into the monitor such as height, weight, and age.  An ICG test will only take about two to five minutes.  This test is absolutely safe and will not cause a patient to feel any different while the test is running.  When the test is complete, an ICG report will be printed and reviewed by your physician.  They will review your results with you and answer any questions you may have.
