What is an Echocardiogram?

An echocardiogram (echo) uses high-frequency sound waves (ultrasound) to create images of your heart. The test is also called echocardiography or diagnostic cardiac ultrasound.

Types of Echocardiograms

• Transthoracic echocardiography
• Stress echocardiography
• Transesophageal echocardiography
• Three-dimensional (3D) echocardiography

What happens during an Echocardiogram?

During an echocardiogram, small electrodes are placed on your chest to monitor your heart’s activity. A technician applies a special gel to your chest, which helps transmit sound waves. A transducer is then moved across your chest to capture images of your heart. In some cases, a Doppler ultrasound may be used to assess blood flow.

Why would I need an Echocardiogram?

You may need an echocardiogram to diagnose heart conditions such as valve problems or congenital defects, evaluate symptoms like chest pain or shortness of breath, monitor heart disease or treatment effectiveness, or assess heart function after a heart attack or surgery.

Who needs an Echocardiogram?

• Individuals with heart symptoms like chest pain or palpitations
• Patients with a history of heart disease or valve issues
• People at high risk due to high blood pressure or diabetes
• Patients preparing for surgery
• Athletes engaging in intense sports
• Individuals with congenital heart issues that need monitoring

What are the risks of an Echocardiogram?

An echocardiogram is generally safe, but potential risks may include:

• Abnormal heart rhythms (arrhythmias) during or after the exercise portion
• Low blood pressure or dizziness
• Chest pain or discomfort
• Rarely, heart attack or stroke

These risks are rare, and the test is performed under medical supervision to ensure safety.

How do I prepare for an Echocardiogram?

Trained technicians conduct these tests in medical offices, hospitals, or emergency rooms. The test typically takes about an hour.
