Pulmonary Embolism - Exams and Tests

Diagnosing pulmonary embolism is difficult, because there are many other medical conditions, such as a heart attack or an anxiety attack, that can cause similar symptoms.

Diagnosis depends on an accurate and thorough medical history and ruling out other conditions. Your doctor will need to know about your symptoms and risk factors for pulmonary embolism. This information, combined with a careful physical exam, will point to the initial tests that are best suited to diagnose a deep vein thrombosis or pulmonary embolism.
