👉 The myocardiogram is a diagnostic test that involves taking an image of the heart muscle. It's used to help diagnose conditions such as heart disease, arrhythmias (arrhythmia is abnormal heartbeat), and atrial fibrillation. The pictures are taken by placing a small camera on the chest or abdomen. The images show how the heart's chambers work together, including the valves that open and close during each beat.
