An echocardiogram is a valuable tool that physicians use to diagnose and manage many forms of heart disease. This painless, non-invasive test uses sound waves to check the heart's structure, movements and blood flow. It is an important tool for checking heart valves and tracking heart conditions over time.

A number of echo technologies are available at Barnes-Jewish West County Hospital, including:

Exercise Stress Echocardiogram: 

During these tests, a patient uses a treadmill to assess how the heart functions during activity.
Pharmacological stress echocardiogram: This is an option for patients who cannot exercise but who require a cardiac stress test. During this test, the patient receives medication that temporarily causes the heart to beat faster, as it does during exercise.

Transesophageal Echocardiogram (TEE): 

This semi-invasive test gives an even clearer picture of the heart than other echo tests. During this test, the patient is sedated and a small probe is placed down the esophagus. Doctors also use TEE to study heart valves or check for blood clots in the heart before interventional procedures or during surgery to monitor patients with existing heart problems.


This is a treatment that involves delivering a short electrical shock to the chest, which helps reset the heart to a normal heart rhythm. A special external defibrillation machine is used. This treatment is performed while the patient is under sedation in our electrophysiology lab. Patients can typically go home the same day of the procedure after being monitored.

Holter Monitors: 

These tests are used to determine if an arrhythmia is occurring and what type and how frequently it is occurring. With Holter monitoring, or 24-hour ECG, the patient wears an external small, portable machine that records changes in heart rhythm throughout the day.

Stress Test: 

A stress test, also called an exercise stress test, is used to gather information about how well your heart works during physical activity. Because exercise makes your heart pump harder and faster than it does during most daily activities, an exercise stress test can reveal problems within your heart that might not be noticeable otherwise.

An exercise stress test usually involves walking on a treadmill while your heart rhythm, blood pressure and breathing are monitored. Your doctor may recommend an exercise stress test if he or she suspects you have coronary artery disease or an irregular heart rhythm (arrhythmia). An exercise stress test may also be used to guide your treatment if you've already been diagnosed with a heart condition.
