• Echocardiogram
    An echocardiogram is a noninvasive (the skin is not pierced) procedure used to evaluate the heart's function and structures.
  • Electrocardiogram
    An electrocardiogram (ECG) is one of the simplest and fastest tests used to evaluate the heart. Electrodes (small, plastic patches that stick to the skin) are placed at certain locations on the chest, arms, and legs. When the electrodes are connected to an ECG machine by lead wires, the electrical activity of the heart is measured, interpreted, and printed out.
  • Electroencephalogram (EEG)
    An EEG is a procedure that detects abnormalities in your brain waves, or in the electrical activity of your brain.
  • Electromyography
    Electromyography measures your muscle response or electrical activity in response to a nerve's stimulation of your muscle. The test is used to help detect neuromuscular abnormalities.
  • Electronystagmography (ENG)
    Electronystagmography (ENG) is a test used to evaluate vertigo and certain other hearing and vision disorders. For this test, electrodes are placed above and below the eye. They record the electrical activity of the muscles that control eye movement.
  • Electrophysiology Studies
    An electrophysiologic study uses small, thin wire electrodes placed directly on the heart to evaluate you for an abnormal heart rhythm.
  • Endometrial Ablation
    Endometrial ablation is a procedure to remove a thin layer of tissue (endometrium) that lines the uterus. It is done to stop or reduce heavy menstrual bleeding. But it is only done on women who do not plan to have any children in the future.
  • Endometrial Biopsy
    An endometrial biopsy is a procedure to take a small tissue sample from the lining of the uterus, called the endometrium. Read on to learn what to expect before, during, and after this procedure.
  • Endoscopic Retrograde Cholangiopancreatography (ERCP)
    Learn details about ERCP, a procedure to diagnose and treat problems in the liver, gallbladder, bile ducts, and pancreas.
  • Endovascular Coiling
    Endovascular coiling is used to block blood flow to an aneurysm.
