Basic Diagnostic Electrophysiology Study

What happens in the electrophysiology study?

The heart is a muscle that pumps blood through a system of vessels (arteries and veins). Heart valves are responsible for sending the blood in the right direction. In addition, the heart has an electrical system, which is responsible for emitting the impulses necessary to pace the heart’s rhythm and adapt it to the body’s needs. Changes in the heart’s electrical system produce rhythm disturbances or arrhythmias. There are slow arrhythmias, called bradycardia, when the heart rate is slower than normal and fast arrhythmias, called tachycardia, when the pace becomes faster. The electrophysiological study allows us to diagnose and treat these.

Medical Protocol


(Variable number of electrocatheters)

  • Left anterior descending artery (4P / 6F)
  • NAV Node / His bundle (3P / 7F)
  • Right ventricular apex (4P / 6F)
  • Coronary sinus (10P / 6F)
  • Quadrapolar 7F (mapping)
  • Right/left femoral vein and artery / Left median/antecubital veins (coronary sinus)
  • Right/left subclavian vein
  • Right jugular vein (exceptional cases)
