Electrophysiology Laboratory Overview


Watch Mayo Clinic cardiologists and others discuss many conditions and treatments related to cardiovascular diseases and cardiovascular surgery.

The Electrophysiology Laboratory, located at each of Mayo Clinic's campuses in Arizona, Florida and Minnesota, provides care for people with heart rhythm disorders (arrhythmias). Doctors at Mayo Clinic have experience and expertise treating arrhythmias with cardiac ablation, implantable devices such as pacemakers and implantable cardioverter-defibrillators (ICDs), and other treatments.

The Electrophysiology Laboratory at Mayo Clinic's campus in Minnesota is active in all aspects of the care of children, adolescents and adults with arrhythmias. Doctors trained in treating children with heart conditions (pediatric cardiologists) provide care for children with arrhythmias at Mayo Clinic's campus in Minnesota.

The Electrophysiology Laboratory at Mayo Clinic's campuses in Arizona and Florida treats adults with arrhythmias. Doctors in heart rhythm disorders may evaluate you and determine whether you should be treated in the Electrophysiology Laboratory or if other therapies are more appropriate for your condition.

Cardiologists trained in the diagnosis and treatment of heart rhythm disorders (electrophysiologists) staff the Electrophysiology Laboratory. The experienced staff uses advanced 3D mapping and imaging systems. The lab staff is actively developing new technologies to treat heart rhythm disorders.

Inpatient electrophysiology studies are performed in state-of-the-art biplane procedure rooms with advanced analysis and recording equipment.

People with several conditions may be diagnosed and treated in the Electrophysiology Laboratory, including:


Doctors in the Electrophysiology Laboratory conduct research in heart rhythm disorders. Learn more about research in the Cardiovascular Research Center.


To make an appointment, you'll need to be referred by your doctor. Not all services may be available at all locations.
