Cardiac Electrophysiology

Three Village Cardiologists' specialize in Cardiac electrophysiology, the study of electrical functions of the heart, which control the speed at which the heart beats. An electrophysiology (EP) study is a test used to understand and map the electrical activity within your heart. Our cardiologists study and diagnose these electrical functions that are unbalanced that can cause arrhythmias or irregular heartbeat. There are four common types of cardiac arrhythmias Tachycardia, Bradycardia, extra beats, and ventricular arrhythmias.

Cardio electrophysiology can assess arrhythmia risks and design treatment, such as medication, pacemaker/defibrillator or ablation procedure. During the cardio electrophysiology study a thin tube called a catheter is inserted into an artery found in the neck, arm or groin and will be guided all the way to the heart under X-ray imagining. There the heart will be tested with different electrical pulses to regulate and measure the hearts reaction.

Why is an EP study done?

  • Have an abnormal heart rhythm (arrhythmia). If you've been diagnosed with an arrhythmia, such as atrial fibrillation, atrial flutter, tachycardia, ventricular tachycardia or supraventricular tachycardia, your doctor may recommend an EP study to better understand how electrical signals move in your heart and how best to treat your condition.
  • Are undergoing cardiac ablation. An EP study is done at the beginning of a cardiac ablation procedure for arrhythmia. Cardiac ablation uses heat or cold energy to create scar tissue in the heart to block erratic electrical signals.
  • Experience a temporary loss of consciousness (syncope). People who experience syncope may undergo an EP study to understand the cause.
  • Have a risk of sudden cardiac death. If you have a heart condition that increases your risk of sudden cardiac death, an EP study may help our cardiologist better understand your risk.
  • Are undergoing heart surgery. If you're preparing for a heart operation in which cardiac ablation may be performed at the same time, our cardiologists may recommend an EP study.

Our Three Village Cardiologists' will guide you through the discussions and benefits of an EP study.

An EP study is performed in the hospital. Before your procedure begins, our cardiovascular specialist will insert an intravenous line into your forearm or hand, and you'll be given a sedative to help you relax. In some situations, general anesthesia may be used instead to place you in a sleep-like state.

Several techniques may be used during an EP study, including:

  • Taking a baseline measurement of the electrical activity in your heart.
  • Using an electrode to cause an abnormal heart rhythm.
  • Using medicines that affect heart function.
  • Mapping the heart in preparation for cardiac ablation.

What you can expect before, during and after the EP study, we encourage you to meet our staff and discover the full range of our cardiovascular medical procedures, studies and services. Please feel free to contact us at our main office in East Setauket, NY, with any questions you might have.

Our mission has always been to provide integrated, comprehensive cardiovascular care to our patients. Our cardiovascular physicians combine knowledge, skill and experience with advanced technology and innovation, brought together for a single purpose — to restore you back to health as quickly and comfortably as possible.
