This test usually follows a stress test and involves the analyzing of sound waves bounced off the heart and recorded by a small sensor placed on the chest. A computer processes the information to produce a one- or two-dimensional moving picture that shows how the heart and heart valves are functioning.
Nuclear stress test
This is an X-ray study that follows the path of radioactive dye, carried by the blood to the heart muscle before and after exercise. This can help define dead and damaged muscle and the extent of the narrowing of an artery.
Medication stress test
This refers to any of the above listed stress tests ordered with a medication that increases the heart rate, for patients who are unable to walk.
Tilt stress test
The tilt table test is a way to find the cause of fainting spells. It involves lying quietly on a bed and being tilted at different angles for a period of time while blood pressure, oxygen level, and electrical impulses in your heart are measured.
