A cardiac perfusion scan measures the amount of blood in your heart muscle at rest and during exercise. It is often done to find out what may be causing symptoms like angina (such as chest pain or pressure).
The most common tests are: 1  EKG (electrocardiogram). This detects and records your heart's electrical activity, with certain EKG results suggesting pericarditis. 2  Chest X-ray. A chest X-ray takes pictures of the inside of the chest, including your heart, lungs and blood vessels. 3  Echocardiography.
