Electrophysiology & Treatment of Arrhythmia

An electrophysiology study or EPS is a diagnostic procedure to look more closely at the electrical function of your heart. It is the most accurate and reliable method of evaluating your heart rhythms and will help your physician determine the treatment option that IS most appropriate for you.

An electrophysiology study can

  • Identify which patients who have had a prior heart attack or MI, are at risk for serious ventricular arrhythmias
  • Help determine which patients may require aggressive treatment to prevent sudden cardiac arrest.
  • Identify individuals whose hearts cannot be induced into dangerous arrhythmias. They appear at lower risk for developing spontaneous, sustained VT that can lead to ventricular fibrillation and sudden cardiac arrest.


Arrhythmia is a disorder characterized by abnormal heart beat such as beating too fast, too slow or irregularly. During arrhythmia, as the heart is not able to pump enough blood to the body, it can lead to organ dysfunction or damage. Most arrhythmias are harmless; however, some are more serious and life-threatening.

There are different types of arrhythmias. Arrhythmias are classified by where they originate (atria or ventricles) and the speed of heart rate.

  • Atrial fibrillation: irregular contraction of upper heart chambers
  • Bradycardia: slow heart beat
  • Conduction disorders: abnormal heart beat
  • Premature contraction: early heart beat
  • Tachycardia: fast heart beat
  • Ventricular fibrillation: irregular contraction of lower heart chambers
