Electrocardiogram (EKG)

An electrocardiogram (EKG) is a non-invasive, painless test that detects and records the electrical activity of the heart. EKGs are used to evaluate signs and symptoms that could indicate heart problems. It takes only a few minutes to perform.


Echocardiogram

A trans-thoracic echocardiogram (TTE) is a non-invasive exam that utilizes high frequency sound waves to produce two-dimensional images of your heart. This test provides information about the size and function of your heart and how well your heart's chambers and valves are working. In addition, by using Doppler ultrasound, one can assess how well blood flows through the chambers and valves of your heart and also estimate pressures within the heart.

With standard transthoracic echocardiography, it can be difficult to see the aorta, valves and certain other parts of your heart. It may be necessary to get a better look at these areas. In these cases, it may be recommended to perform a transesophageal echocardiography (TEE). This test is performed in a hospital under mild sedation and involves an ultrasound probe being inserted into your esophagus to get a more detailed image of your heart.


Stress testing

Please wear loose fitting clothes an soft-soled shoes for the test. Stress testing provides information about how your heart works during physical stress. During a stress test, you exercise (walk or run on a treadmill). The treadmill belt moves faster every 3 minutes. The longer you can exercise, the more useful the test, BUT you are always in charge and the test will be stopped whenever you say so. A stress test can reveal problems within your heart that might not be noticeable otherwise. The test is most useful in people experiencing chest pain who have risk factors for coronary artery disease. Sometimes it is combined with other tests that take pictures of the heart using radioactivity or sound waves. For those unable to walk, a chemical can be administered that speeds up the heart and opens the blood vessels thus simulating exercise.


Holter and home event monitoring

Holter and event monitors are medical devices that record the heart's electrical activity and are used to diagnose arrhythmias.

Holter and event monitors also are used to detect silent myocardial ischemia. A Holter monitor is a portable device that is roughly the size of an iPod. It records all of your heartbeats on tape for a continuous period of 24-48 hours and is typically ordered when patients complain of symptoms like dizziness, syncope, or palpitations. A Holter monitor has electrodes that are attached to your chest with adhesive and then are connected to a recording device. Unlike Holter monitors, event monitors do not continuously record the heart's electrical activity. They only record when symptoms occur. For many event monitors, you need to start the monitor when you feel symptoms. Information captured on the monitor's recording device can be used to determine if you have a heart rhythm problem.
