Your child's physician may have heard an abnormal heart sound called a rub, which occurs when there is irritation of the pericardial membranes. In addition to a complete medical history and physical examination, diagnostic for pericarditis may include:
- blood tests (to evaluate the degree of inflammation).
- chest x-ray - a diagnostic test which uses invisible X-ray energy beams to produce images of internal tissues, bones, and organs onto film.
- echocardiography (echo) - a procedure that evaluates the structure and function of the heart by using sound waves recorded on an electronic sensor that produce a moving picture of the heart and heart valves.
