Tests & Screenings

Understanding the source of your heart symptoms is one of the first steps toward good heart health. At MacNeal 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 MacNeal.

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.


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.

Electroencephalogram (EEG)

An electroencephalogram (EEG) is a test that uses electrodes placed on the scalp to detect the electrical activity of the brain.

Thallium and dobutamine testing

Thallium and dobutamine are two medications that are used to facilitate cardiac testing. Thallium is a radioactive substance that travels through the vessels and helps make the path the blood has traveled visible while dobutamine chemically increases the heart rate for those who are unable to walk on a treadmill.
