An echocardiogram, often called an 'echo,' is one of the most commonly performed cardiac imaging tests. This safe, non-invasive procedure provides valuable information about your heart's structure and function.
How Does an Echo Work?
An echocardiogram uses ultrasound technology - the same type used to view babies during pregnancy. A small device called a transducer sends sound waves through your chest. These waves bounce off your heart structures and return to the transducer, creating moving images on a screen.
What Can an Echo Show?
- Size and shape of your heart chambers
- Heart valve function
- Heart muscle movement and pumping strength
- Blood flow through your heart
- Congenital heart defects
- Blood clots or tumors
Types of Echocardiograms
**Transthoracic Echo (TTE):** The standard test where the transducer is placed on your chest.
**Transesophageal Echo (TEE):** A probe is passed down your throat for clearer images. This requires sedation.
**Stress Echo:** Images are taken before and after exercise or medication that makes your heart beat faster.
During Your Echo
- You'll lie on an exam table
- Gel is applied to your chest
- The sonographer moves the transducer across your chest
- You may be asked to change positions or hold your breath briefly
- The test typically takes 30-60 minutes
After Your Echo
You can resume normal activities immediately. A cardiologist will interpret the images and send results to your doctor, usually within 24-48 hours.
