Most patients know that something is not right, yet they have a problem describing their uneasiness. Also the pulmonary embolism symptoms are very vague; hence it is likely that experts identify the problem as anxiety rather than PE.
When a patient is brought in, the doctor checks the heart, lungs and legs of the patient and measures the blood pressure, pulse rate and breathing rate. An ECG and chest x-ray are often taken.
The most commonly used diagnostic test for deep vein thrombosis and pulmonary embolism is the venous ultrasound examination which is a non-invasive procedure. Another test used to establish PE diagnosis is the rapid-speed chest computed tomography (CT) scan. This directly captures the images of the blood clots that block the pulmonary artery.
A blood test that is done to screen PE is the D-dimer test. If this test is normal, it is highly unlikely that the person has PE.
