Tests and diagnosis discussion for Dilated cardiomyopathy:

Once symptoms appear, the condition may be tentatively diagnosed based on a physical examination and a patient's medical history. More often, though, further examination is needed to differentiate dilated cardiomyopathy from other causes of heart failure.

A firm diagnosis typically requires a chest x ray to show whether the heart is enlarged, an electrocardiogram to reveal any abnormal electrical activity of the heart, and an echocardiogram , which uses sound waves to produce pictures of the heart.

Other, more specific tests may also be needed. These include:

  • A radionuclide ventriculogram. This involves injecting low-dose radioactive material (usually equal to that in a set of chest x rays) into a vein, through which it flows to the heart. Pictures are generated by a special camera to show how well the heart is functioning.

  • A cardiac catheterization . In this procedure, a thin plastic tube is inserted through a blood vessel until it reaches the heart. A dye is injected and x rays taken to assess the heart's structure and function.
