ETMC Cardiovascular Institute

First in the hearts of East Texas



The electrophysiology (EP) laboratory of the ETMC Cardiovascular Institute is equipped to care for all types of patients with problems with the electrical system of the heart. In fact, ETMC was the first electrophysiology program in East Texas to offer ablation therapy in treating cardiac arrhythmias.

ETMC's EP lab also includes a 3-D Ensite Mapping System, which provides 3-D images of the heart.

EP studies are performed by a cardiologist who has completed specialized training to treat disturbances in the conduction system of the heart. This specialist is called an "electrophysiologist."

Electrophysiology services include the following:


  • Electrophysiology studies allow the electrophysiologist to diagnose and treat several types of abnormal heart arrhythmias.
  • Ablations are procedures that allow the electrophysiologist to stop several types of abnormal heart arrhythmias using a small catheter.
  • Pacemakers are implanted in the EP lab to help patients maintain a normal heart rhythm.
  • ICD (implantable cardiac defibrillator) implants help patients with life-threatening heart arrhythmias.
  • Tilt table tests allow the electrophysiologist to diagnose and treat patients who lose consciousness or feel light-headed from unknown causes.
