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 participates in many clinical research trials, giving patients access to a wide range of both standard and leading-edge treatments.
Among the First to Perform Atrial Fibrillation Ablations
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
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.
Our Experienced Expertise in 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
Working Closely with Patients' Individual Needs
Treatment options often are complex, and our
physicians strive to provide individualized recommendations in
clear, understandable language to help patients choose among
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.
Greater Access to Our Physicians and Services
OhioHealth’s expanded network of arrhythmia clinics means patients have greater access to our expert physicians and comprehensive services.
Relying on their advanced training and vast experience, our arrhythmia experts perform the latest and most advanced cardiac arrhythmia treatments and are at the forefront of several approaches to treating the most complex arrhythmias.
OhioHealth electrophysiology services include:
- Implantation and extraction of cardiac pacemakers and implantable cardiac defibrillators
- Laser-assisted lead extractions that are minimally invasive and can ablate scar tissue during the procedure
- Non-invasive cardioversion procedures and tilt table tests
- Comprehensive diagnostic electrical studies
- Advanced device therapy for the treatment of heart failure
- Atrial fibrillation ablations
- Ventricular tachycardia ablations
- Left atrial flutter ablations
Some of our leading edge therapies, include:
- Radiofrequency ablation, cryoablation and a hybrid technique performed by a cardiothoracic surgeon and an electrophysiologist
- Left atrial appendage (LAA) closures using the LARIAT device, and the recently FDA-approved Watchman closure device
- Technological assets, such as three-dimensional mapping systems, intracardiac echocardiogram and advanced hemodynamic support capabilities to assist in the ablation of complex arrhythmias
- Involvement in numerous multicenter clinical trials
