A BioZ, sometimes called an ICG test, is a completely noninvasive test that provides your physician with information about your heart's ability to deliver blood to the rest of your body, the force your heart has to pump against with each heartbeat and the amount of fluid in your chest.

Why might I need a BioZ?

If you are an outpatient and are being treated for high blood pressure, heart failure, lung disease, you have a pacemaker or are on any cardiac drugs, a BioZ test may provide helpful information to your physician when he or she is making decisions about your drug therapy or pacemaker settings. BioZ monitoring may also be used if you are an inpatient to assist your physician in his or her assessment and treatment of  your condition.

What happens during a BioZ?

Before the test begins, you may need to be weighed. Having your correct height and weight is essential to getting an accurate test result.

You will then be asked to loosen your clothes if needed and lay down. The technician will enter your information into the BioZ cart and prepare the wires, electrodes and blood pressure cuff.

The technician will then place four BioZ electrodes on your body. One electrode will be placed on each side of your neck and on each side of your chest. The technician will also put a blood pressure cuff on your arm. Wires are then connected to the electrodes. The machine will begin to take measurements of your heart's function for the BioZ report.

When the technician has a good recording, he or she will save it, unhook you and you're done. You'll be able to get up, adjust your clothing and leave or go on to your next test.

What is the difference between a BioZ/ICG and an EKG?

A BioZ/ICG measures the mechanical function of your heart.

An EKG measures the electrical function of your heart.

When will I know the results of my BioZ?

You will need to get results of your test from your physician's office.

After the BioZ is complete, we'll make the test available to your physician. Your physiciail will be able to review the test and let you know your results.
