Jefferson University Hospitals


Renowned radiologists and cardiologists in Jefferson's noninvasive cardiovascular diagnostic testing laboratories use an electrocardiogram to assess the electrical activity of the heart to detect arrhythmias, coronary artery disease and heart muscle damage.

Signal-Averaged Electrocardiogram

Our cardiologists will use signal-averaged electrocardiogram to assess faint electrical activity of the heart not detectable with a regular electrocardiogram to diagnose arrhythmias.

Stress Test (Exercise Electrocardiogram)

An exercise electrocardiogram, also known as a stress test, can help find changes in your heart while you exercise. Renowned radiologists and cardiologists will perform this test to assess your heart following a cardiac event, such as a heart attack, or to assess your ability to exercise if you have or are suspected to have coronary artery disease.

You will either walk on a treadmill or pedal on a stationary bicycle while being monitored by an electrocardiogram machine. Your Jefferson physician will use the results of this test to assess your heart health and recommend a personalized treatment plan or rehabilitation program if necessary.
