Heart Nuclear Stress Test Machine

Nuclear scanning of the heart shows how well blood flows to the heart muscle.

Heart nuclear stress test machine.

A traditional nuclear stress test uses a gamma camera a donut shaped imaging machine to take pictures of your heart after injection of a radioactive tracer. Compared with an exercise stress test a nuclear stress test can help better determine your risk of a heart attack or other cardiac event if your doctor knows or suspects that you have coronary artery disease. A nuclear stress test is a study aimed at measuring whether the blood flow to your heart muscle is normal or abnormal. Cardiac nuclear medicine imaging evaluates the heart for coronary artery disease and cardiomyopathy diseases of the heart muscle.

The speed and resistance of the exercise machine may be increased over time. The heart pumps blood to every part of the body and it too needs blood to work just like any other muscle. It also may be used to help determine whether the heart has been damaged by chemotherapy or radiotherapy. Isotope stress test nuclear stress test.

This uses a radioactive isotope injected intravenously to measure blood flow to the heart during exercise. In rare instances some people have a treatable allergic reaction to the tracer. You will exercise or receive medicine to stress your heart. Bring it to the test and make sure the health care team monitoring your stress test knows that you use.

If you have coronary heart disease you may have chest pain during the stress test. The patient is scanned at rest and pictures are obtained. Sometimes due to blockage within one or more coronary arteries blood flow can be partially impeded or fully blocked from reaching the heart muscle tissue. How does it work.

Your heart rate heart rhythm and blood pressure will be monitored closely during the test. The study utilizes a radioactive tracer to create an image of how well blood is reaching your heart muscle both during exercise and while at rest. Nuclear heart scans have few risks. Talk to your doctor and the technicians performing the.

This uses medicine rather than exercise to determine if the heart is functioning properly. A nuclear stress test uses radioactive dye and an imaging machine to create pictures showing the blood flow to your heart. It s usually done in conjunction with an exercise stress test on a treadmill but can also be performed using medicines such as regadenoson and dobutamine that effectively simulate the effects of exercise on the heart. During a nuclear stress test with exercise you will walk on a treadmill or pedal on a stationary bicycle.

A nuclear stress test is one of several types of stress tests that may be performed alone or in combination. Medicine can help relieve your chest pain. Next you either exercise or receive medicine to simulate exercise and will have a second scan to obtain pictures after stress.
