Echocardiogram. Sound waves can create moving images of the beating heart. An echocardiogram can help your doctor to check the size and functioning of the right ventricle, and the thickness of the right ventricle's wall. An echocardiogram can also show how well your heart chambers and valves are working. Doctors may also use this to measure the pressure in your pulmonary arteries.
Chest X-ray. A chest X-ray can show images of your heart, lungs and chest. This test can show enlargement of the right ventricle of the heart or the pulmonary arteries, which can occur in pulmonary hypertension. This test can also be used to identify other conditions that may be causing pulmonary hypertension.
Electrocardiogram (ECG). This noninvasive test shows your heart's electrical patterns and can detect abnormal rhythms. Doctors may also be able to see signs of right ventricle enlargement or strain.
Right heart catheterization. After you've had an echocardiogram, if your doctor thinks you have pulmonary hypertension, you'll likely have a right heart catheterization. This test can often help confirm that you have pulmonary hypertension and determine the severity of your condition.
