The Echocardiogram:
A Routine Test for Diagnosing Heart Disease
The echocardiogram, or echo, is a non-invasive procedure used to assess heart function and detect various forms of heart disease. This test can be performed by a cardiologist (heart specialist) to produce a graphic outline of the heart’s movement. During the test, high-frequency sound waves provide the cardiologist with pictures of the heart’s valves and chambers to evaluate its pumping action. Echocardiograms do not involve any exposure to radiation.
What happens during the test?
Before the test, the patient changes into a hospital gown and a sonographer (cardiac technician) applies three electrodes (small, sticky patches) to the chest. These electrodes are attached to an electrocardiograph monitor, or EKG, which charts the heart’s electrical activity.
The sonographer places a wand with a small amount of gel over various places on the patient’s chest. The wand does not cause any pain and the gel helps to produce clearer pictures. Overall, the procedure takes about 40 minutes and does not cause any discomfort to the patient.
What does the test reveal?
The results of an echocardiogram enable physicians to evaluate heart murmurs and monitor patients who have had heart attacks. The test also reveals heart chamber size, valve function and heart strength. While the results may show some minor abnormalities, they can also reveal more serious signs of heart disease that require further evaluation by a specialist.
The expert cardiologists with the Penn Cardiac Care team are experienced in interpreting the results of an echocardiogram test and recommending a treatment plan for heart patients.
