Electrophysiology Laboratory Overview


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

Mayo Clinic in Arizona, Florida and Minnesota each offer an electrophysiology laboratory. People might be treated in one of these labs if they have heart rhythm disorders (arrhythmias). Our doctors are experts in treating arrhythmias with cardiac ablation, implantable devices such as pacemakers and implantable cardioverter-defibrillators (ICDs), and other methods.

In the electrophysiology laboratories, cardiologists trained in the diagnosis and treatment of heart rhythm disorders (electrophysiologists) use advanced 3D mapping and imaging systems. If you're in the hospital and need an electrophysiology study, you'll be taken to a special procedure room with state-of-the-art electrophysiology equipment that allows for advanced analysis and recording.

The electrophysiology laboratory at Mayo Clinic in Minnesota is active in all aspects of the care of children, adolescents and adults with arrhythmias. The staff includes doctors trained in treating children with heart conditions (pediatric cardiologists).

The electrophysiology laboratories at Mayo Clinic in Arizona and Florida treat adults with arrhythmias. You doctor may evaluate you and refer you to the lab or recommend other therapies.

Who might benefit from treatment in an electrophysiology laboratory?

Conditions diagnosed and treated in an electrophysiology laboratory include:

Innovative research

Mayo Clinic's electrophysiologists research and develop new processes and technologies to treat heart rhythm disorders. Their many advances include surgical approaches and electrophysiologic mapping techniques for supraventricular arrhythmias. These techniques have been widely adopted for the benefit of people with heart rhythm disorders.
