Electrophysiology is used to diagnose and treat patients with arrhythmias, which are commonly known as irregular heartbeats. Arrhythmias may cause chest pain, dizziness, heart palpitations, or fainting.


  • Electrophysiology studies assess irregular heart rhythms to determine the cause. The study involves sending electrical impulses to the heart to determine the origin of the abnormal rhythm. A thin tube called a catheter is inserted into a blood vessel that leads to the heart. The heart’s electrical conduction system is measured and evaluated to provide a diagnosis.
  • Cardiac ablation uses radiofrequency energy to treat small areas of tissue that are causing abnormal heart rhythms. The procedure involves inserting a catheter to the problem area, using advanced technology to guide the precise treatment of rhythm abnormality.
  • Pacemakers and implantable cardiac defibrillators (ICDs) are used to monitor and regulate heart rhythms.
  • Cardiac resynchronization therapy involves implanting pacemaker wires in the heart’s left and right ventricles to restore the heart’s synchronized pumping function.
