The human heart depends on a complex electrical network to maintain a normal rhythm. When that network is disrupted, serious arrhythmias (abnormal heart rhythms) can occur, resulting in an irregular pulse, rapid heart activity, lightheadedness or fainting (syncope).

Highly trained electrophysiologists at OhioHealth use state-of-the-art technology to diagnose, treat and cure electrical disorders of the heart.

Electrophysiology is one of the fastest growing areas in heart and vascular medicine, and OhioHealth continues to expand both diagnostic and treatment capabilities to provide patients with the best and most innovative care.

OhioHealth's electrophysiology program provides expert consultation and care for a variety of rhythm disturbances, including:

  • atrial fibrillation
  • atrial flutter
  • supraventricular tachycardia
  • ventricular tachycardia
  • bradyarrhythmia
  • syncope

OhioHealth participates in many clinical research trials, giving patients access to a wide range of both standard and leading-edge treatments.

Leaders in Ablation

Catheter ablation is a minimally invasive technique used to eliminate the abnormal heart tissue responsible for an arrhythmia. During ablation, a flexible tube (catheter) is threaded through blood vessels into the heart. The catheter is used to identify abnormal signals and deliver ablation energy to eliminate the heart tissue responsible for the abnormal signals.

OhioHealth offers a full range of ablations and is one of the first hospital systems in central Ohio to perform atrial fibrillation ablations.

We currently use both radiofrequency ablation and cryoballoon ablation techniques to treat atrial fibrillation. In some cases, patients have the option of a combined, hybrid approach.

  • Radiofrequency ablation uses an RF energy source to heat the tip of the catheter in precise locations to isolate the pulmonary veins (the most common source of atrial fibrillation) and to eliminate other electrically abnormal tissue in the heart.
  • Cryoablation uses liquid nitrous oxide to cool a specially designed balloon to electrically isolate the pulmonary veins.

Innovative Device Therapy

We are experienced in implanting and managing cardiac pacemakers, implantable defibrillators and resynchronization devices for heart failure patients. We perform laser-assisted lead extractions and left atrial appendage closures in a hybrid operating room specifically designed to minimize risk and ensure the best outcomes for patients undergoing these complex procedures.

Patient-Centered Care 

Treatment options often are complex, and our physicians strive to provide individualized recommendations in clear, understandable language to help patients choose among various therapies.

Our patient-centered approach to care earns us consistently high scores in patient satisfaction - before, during and after treatment. We make ourselves available to answer questions quickly, and we continue to follow patients as they recover.
