A MUGA scan is a nuclear medicine scan and does not involve magnetic fields as MRI's do.
When the sinoatrial node, the pacemaker of the heart, fails, the atrioventricular node takes over as pacemaker. It is located between the atria and ventricles in the heart. It paces the heart at about 60 beats per minute.

A pacemaker is an electronic device implanted to regulate the heart after heart attacks. The neurons from the hosts body signal the pacemaker to keep the heart beating at 60-80 bpm.ÊÊ

A MUGA scan is performed in a hospital nuclear medicine department or in an outpatient facility
The MUGA scan is performed to determine if the heart's left and right ventricles are functioning properly and to diagnose abnormalities in the heart wall.
A normal MUGA scan should not demonstrate areas of akinesis (lack of movement), or hypokinesis (decreased movement) of the heart muscle walls
A multiplegated acquisition (MUGA) scan is a variation of this test.
It takes approximately 30 minutes to one hour
The MUGA scan stands for Multiple Gated Acquisition Scan and is an extremely useful tool to assess the function of the heart. It's also noninvasive. The scan provides a moving image of the beating heart. From this image medical professionals can make conclusions about the health of the cardiac ventricles.
It helps the radioisotope bind to the RBC's.
The patient may resume normal activities immediately following the test
The pictures are taken via gamma camera driven by a computer program
