The Electrophysiology Program, part of the interdisciplinary Heart Institute at Cincinnati Children’s, specializes in diagnosing and treating complex arrhythmias.

An electrophysiology study involves placing electrodes within the heart by the way of catheters, which are plastic tubes the size of a piece of spaghetti. The catheters are placed through the veins of the body, most commonly those in the upper part of the leg, and guided to the heart.

Electrical activity inside the heart can be measured and stimulation of the heart can be performed to assess the electrical function of the heart and to initiate abnormal heart rhythms. Frequently, this is combined with “catheter ablation,” the targeted destruction of a small area of the heart responsible for heart rhythm abnormalities.

Integrated Treatment

The Electrophysiology Program provides comprehensive non-invasive and invasive services, including:

Treatment can include:

  • Insertion of a pacemaker, a small, battery-powered medical device designed to electrically stimulate the heart muscle in an effort to restore a more normal heart rhythm
  • Implanted cardioverter defibrillators
  • Leading-edge surgical techniques such as cryothermal catheter ablation
