what test is used to diagnose cardiomyopathy
Your doctor will conduct a physical examination, take a personal and family medical history, and ask when your symptoms occur â for example, whether exercise brings on your symptoms. If your doctor thinks you have cardiomyopathy, you may need to undergo several tests to confirm the diagnosis. These tests may include: 1  Chest X-ray. 2  An image of your heart will show whether it's enlarged. 3  Echocardiogram. 4  An echocardiogram uses sound waves to produce images of the heart.
