Electrophysiology (EP)

Cardiac electrophysiology focuses on the diagnosis and treatment of heart rhythm disorders, or arrhythmias.

The Electrophysiology (EP) Program at Allegheny Health Network (AHN) Cardiovascular Institute features sophisticated diagnostic equipment and the most up-to-date technology to pinpoint the cause of your arrhythmia. This critical information guides our team of heart rhythm specialists as they develop the most effective treatment plan for your unique heart problem.

Advanced diagnostic procedures

Our cardiology and heart rhythm specialists perform a variety of diagnostic procedures to evaluate your heart’s electrical system and pinpoint the cause of your symptoms.

These diagnostic tests include:

Electrocardiogram (EKG/ECG)

An ECG is a quick and painless test that measures the electrical activity of the heart using electrodes placed on the chest. This will show doctors whether the heart is beating normally.

Cardiac monitor

A cardiac monitor is a small, battery-operated device that is attached to your chest with an adhesive patch and worn continuously for 24 hours or longer. The monitor records the electrical activity of your heart during this time.

Implantable loop recorder

An implantable loop recorder is a small electronic device that is placed under the skin of your chest. The device continually records your heart’s electrical activity for up to three years. Your doctor uses special equipment to download information from the device to monitor your heart.

Tilt-table test

A tilt-table test is used to assist in finding the cause of unexplained problems, such as fainting, dizziness, or low blood pressure when standing. For this test, you will be safely secured to a table that moves you from a lying position to an upright position. Your heart rhythm and blood pressure will be monitored during the test.

Electrophysiology (EP) study

An electrophysiology study is used to evaluate your heart’s conduction system. During an EP study, your doctor uses long wires (catheters) to stimulate and record your heart’s electrical activity and pinpoint problem areas.

What to expect during an electrophysiology (EP) study procedure

Before an electrophysiology test, your doctor will insert an IV line into your hand or arm. Electrodes or monitors are placed on your chest to keep track of your heartbeat during the procedure. Before it begins, you’ll be given a sedative to help you relax.

During the procedure, catheters are inserted through the groin using IVs and placed in three or more areas on the heart. The catheters record and send electrical signals to your heart.

An EP study is performed without incision, stitches, or open-heart surgery. This procedure can take one to four hours, depending on which tests are performed. Most patients are able to return home on the same day as their procedure.
