Get StartedTests and diagnosis
By Mayo Clinic staffYour doctor may diagnose Dressler's syndrome based on your medical history and signs and symptoms, by listening to your heart, and sometimes by using blood tests. Other diagnostic tests may include:
- Echocardiogram. An echocardiogram uses sound waves to produce an image of your heart. This test allows your doctor to see if fluid is collecting around your heart.
- Electrocardiogram. An electrocardiogram records the electrical impulses in your heart through wires attached to the skin. Certain changes in the electrical impulses may mean there's pressure on your heart.
- Chest X-ray. This X-ray can help detect fluid building up around the heart or lungs and can help exclude other causes of your symptoms, such as pneumonia.
