Believe it or not, your heart emits electrical impulses. They're generated by the sinus node of your heart—a collection of electrical cells in the upper right atrium of the heart. And these electrical impulses ultimately generate your heart beat. Electrophysiology (EP) is the science of understanding, diagnosing, and treating these electrical activities in the heart. Treatments include:

  • Ablation for atrial fibrillation (irregular heart beat): A catheter neutralizes heart tissue around the pulmonary veins, stopping abnormal electrical signals from reaching the heart
  • Implantable cardioverter defibrillators (ICDs) and pacemakers: Devices that are implanted to correct irregular heart beats or regulate the heart rhythm impulses of electricity

The electrophysiology program at St.Vincent Heart Center of Indiana is growing. As the number of patients diagnosed with atrial fibrillation (A-fib) continues to increase, the A-Fib Center of Excellence at St.Vincent Heart Center of Indiana continues to provide a comprehensive offering of diagnostic tests, treatments and select surgeries. In 2009, St.Vincent Heart Center performed 2,166 EP procedures and continues to do so with above-average success rates.
