High-frequency sound waves (called ultrasound) are used to exam the size, shape, and motion of the heart.
In addition to the standard test, there are specialized echocardiograms:
.
The test shows:
- Four chambers of the heart
- Valves
- Blood vessels entering and leaving the heart
- Sac that surrounds the heart
The procedure is most often done to:
- Evaluate a heart murmur
- Diagnose and determine the extent of valve conditions
- Find abnormalities in the heart's structure
- Measure the size and thickness of the heart and its chambers
-
Assess motion of the chamber walls and the extent of damage to the heart muscle after a
heart attack
- Assess how different parts of the heart are functioning in people with chronic heart disease
- Determine if fluid is collecting around the heart
- Identify the presence of tumors in the heart
- Assess and monitor congenital defects
- Evaluate a response to treatment or procedure
- Evaluate blood flow through the heart
- Assess if the heart or major blood vessels have been damaged by a traumatic injury
- Evaluate heart function and diagnose heart and lungs abnormalities in critically ill patients
- Evaluate chest pain
- Evaluate for presence of blood clots within heart chambers
If you have the following conditions, you may need transesophageal echocardiography, rather than the standard echocardiogram:
- Barrel chest
- Certain lung diseases
- Obesity
Evidence to date shows no risk from standard echocardiograms.
You're doctor will most likely do the following:
- Physical exam
- Electrocardiogram (ECG, EKG)—a test that records the heart's activity by measuring electrical currents through the heart muscle
None. With the endoscopic test, you may be given a mild sedative.
A gel is applied to your chest. This gel helps the sound waves to travel. The technician then presses a small, hand-held device (called a transducer) against your skin. The transducer sends high-frequency sound waves toward your heart. The sound waves are then reflected back to the device. The waves are converted into electrical impulses. These impulses become an image on the screen.
The technician can capture a still image or videotape moving images. To obtain clearer and more complete images, the technician may move the transducer to different areas of your chest. You may be asked to change positions and slowly inhale, exhale, or hold your breath.
The gel is removed from your chest.
You can return to normal activities.
The images are analyzed by a specialist. Based on these findings, your doctor will make recommendations for treatment.
