An echocardiogram, also known as an echo test, is a type of ultrasound test that uses sound waves to create a moving picture of your heart. It is used to assess the size and shape of your heart, as well as the motion of your heart’s valves and walls. Who performs an echo test?
An echo test is usually performed by a cardiologist, a doctor who specializes in diagnosing and treating heart conditions.
What are the different types of echocardiogram?
There are three main types of echocardiogram: transthoracic, transesophageal, and exercise stress.
What techniques are used in echocardiography?
Echocardiography uses sound waves to create images of the heart. The sound waves are sent through a transducer, which is a device that converts sound waves into electrical signals. The electrical signals are then processed by a computer to create images of the heart.
How long does an echocardiogram take?
The length of an echocardiogram depends on the type of test being performed. A transthoracic echocardiogram typically takes about 30 minutes, while a transesophageal echocardiogram can take up to an hour. An exercise stress echocardiogram can take up to two hours.
What is an echocardiogram vs. an EKG?
An echocardiogram is an ultrasound test that uses sound waves to create images of the heart. An EKG, or electrocardiogram, is a test that measures the electrical activity of the heart.
When would I need an echocardiogram?
An echocardiogram may be recommended if you have symptoms of a heart condition, such as chest pain, shortness of breath, or an irregular heartbeat. It may also be recommended if you have a family history of heart disease.
What does an echocardiogram show?
An echocardiogram can show the size and shape of the heart, as well as the motion of the heart’s valves and walls. It can also show any areas of the heart that are not functioning properly.
How is a transthoracic echocardiogram done?
A transthoracic echocardiogram is done by placing a transducer on the chest. The transducer sends sound waves through the chest wall and into the heart. The sound waves are then reflected back to the transducer, which creates images of the heart.
Preparing for a transthoracic echo
Before a transthoracic echocardiogram, you may be asked to remove any jewelry or clothing that may interfere with the test. You may also be asked to fast for several hours before the test.
What to expect during a transthoracic echo
During a transthoracic echocardiogram, you will lie on your back on an exam table. The technician will place a transducer on your chest and move it around to create images of your heart.
How is a transesophageal echocardiogram done?
A transesophageal echocardiogram is done by placing a transducer at the end of a flexible tube. The tube is inserted through the mouth and into the esophagus. The transducer sends sound waves through the esophagus and into the heart.
Preparing for a transesophageal echo
Before a transesophageal echocardiogram, you may be asked to fast for several hours. You may also be asked to take a sedative to help you relax during the test.
What to expect during a transesophageal echo
During a transesophageal echocardiogram, you will lie on your back on an exam table. The technician will insert a flexible tube through your mouth and into your esophagus. The transducer at the end of the tube will send sound waves through the esophagus and into the heart.
How is an exercise stress echocardiogram done?
An exercise stress echocardiogram is done by having you exercise on a treadmill or stationary bike while the technician takes images of your heart.
Preparing for an exercise stress echo
Before an exercise stress echocardiogram, you may be asked to fast for several hours. You may also be asked to wear loose-fitting clothing and comfortable shoes.
What to expect during an exercise stress echo
During an exercise stress echocardiogram, you will be asked to exercise on a treadmill or stationary bike while the technician takes images of your heart.
How do I get the results of my test?
The results of your echocardiogram will be sent to your doctor, who will discuss the results with you.
What should you not do before an echocardiogram?
Before an echocardiogram, you should not eat or drink anything for several hours. You should also avoid wearing any jewelry or clothing that may interfere with the test.
