An exercise echocardiogram is a procedure in which ultrasound, or sound wave technology, is used to asses the heart's response to stress or exercise.

An electrophysiologic study uses small, thin wire electrodes placed directly on the heart to evaluate you for an abnormal heart rhythm.

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.

A bone density test is used to measure the bone mineral content and density. It may be done using X-rays, dual-energy X-ray absorptiometry (DEXA or DXA), or a special CT scan that uses computer software to determine bone density of the hip or spine.

Fluoroscopy is a type of imaging tool. It looks at moving body structures. It’s much like an X-ray "movie."

A carotid artery duplex scan is an imaging test to look at how blood flows through the carotid arteries in your neck.

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.

Evoked potentials studies measure electrical activity in the brain in response to stimulation of sight, sound, or touch.

A nerve conduction velocity test measures how fast electrical impulses move through your nerves. The test is used to identify nerve damage.

An EEG is a procedure that detects abnormalities in your brain waves, or in the electrical activity of your brain.
