  • Collaborative approach. Electrophysiologists work closely with other doctors, including cardiologists and cardiac surgeons, in the Heart Rhythm Clinic to understand your heart condition and recommend the treatment options that will work best for you. This team approach helps ensure that you receive personalized, quality care.
  • Expertise in all arrhythmias, including rare and complex types. Mayo Clinic doctors use EP studies to diagnose and treat a variety of atrial and ventricular arrhythmias, including those that are very rare and difficult to treat.
  • Advanced technology. Mayo Clinic doctors performing EP studies use the most advanced technology to understand your condition and guide treatment decisions.

    Advanced mapping systems, including multielectrode mapping and 3D heart mapping, are used during cardiac ablation procedures. These innovative techniques help your care team accurately determine where to apply the heat (radiofrequency energy) or cold (cryoablation) treatments to correct abnormal heartbeats.
