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.
