Tests & Screenings

Understanding the source of your heart symptoms is one of the first steps toward good heart health. At Westlake Hospital, we offer a wide range of heart tests and screenings all at one convenient location. Below is a list of common diagnostic tests and heart disease screenings you may receive at Westlake.

30-Day Cardiac Event Monitor

Cardiac event monitors are small portable devices worn by a patient during normal activity for up to 30 days. The device has a recording system capable of storing several minutes of your electrocardiogram (EKG) record. Cardiac event monitors have primarily been used to diagnose and evaluate cardiac arrhythmias.

24-Hour Holter Monitors

24-hour Holter monitors are battery-operated ECG devices, which monitor and record the heart's electrical activity for 24 hours.

Arterial Vascular Study Lower Extremity

An arterial vascular study of the lower extremity typically involves inflating blood pressure cuffs on the legs while recording the pulse sounds through a Doppler transducer.

Dobutamine Stress test with Echocardiography Imaging or Nuclear Imaging

Dobutamine is a medication used to facilitate cardiac testing by chemically increasing the heart rate for those who are unable to walk on a treadmill. Nuclear imaging uses a radioactive substance that travels through the vessels to highlight areas of decreased or normal blood flow. 


An echocardiogram uses sound waves to produce images of your heart. This commonly used test allows your doctor to see how your heart is beating and pumping blood.

Electrocardiogram (ECG)

An electrocardiogram (ECG) is a test in which electrodes on the chest are used to monitor and record the electrical activity of the heart.

Exercise Stress Test

An exercise stress test, sometimes called a treadmill test, helps your doctor find out how well your heart handles work. As your body works harder during the test, it requires more oxygen, so the heart must pump more blood. The test can show if the blood supply is reduced in the arteries that supply the heart.

Lexiscan Nuclear Stress Test

Lexiscan is a prescription medication used in a cardiac nuclear stress test. It works by increasing blood flow in the coronary arteries. Lexiscan is given by IV in preparation for a myocardial perfusion imaging (MPI) test. This uses a special camera to take pictures of your heart, giving your doctor detailed information about blood flow into your heart.

Transesophageal Echocardiography (TEE)

TEE uses high-frequency sound waves (ultrasound) to make detailed pictures of your heart and the arteries that lead to and from it. Unlike a standard echocardiogram, the echo transducer that produces the sound waves for TEE is attached to a thin tube that passes through your mouth and into your esophagus.
