What is a hemodynamic test?

A hemodynamic tilt test is used to check your blood circulation and to see how well your heart is working. It is done using nuclear imaging. You may also hear the test referred to as a technetium (pronounced tek-nee-see-um) hemodynamic test.

Why do I need this test?

Your doctor will use the information collected during the test to find the cause of your syncope or circulation disorder. The test results will also help determine your best plan of care.

What is syncope?

Syncope (pronounced “sin ko pea”) is commonly called fainting or passing out. It happens when there is a temporary decrease in the blood flow to your brain. Syncope can happen if you have a sudden drop in blood pressure, heart rate or changes in blood volume or distribution. An episode usually ends quickly, but you may feel confused afterwards.

Many people who have syncope have a medical condition related to the heart, nervous system or blood flow to the brain.
