The Electrophysiology and Pacing Studies Unit is one of the most active departments in Greece. In the field of electrophysiology, electrophysiological studies and therapeutic interventions of supraventricular and ventricular tachycardias ablation are performed. The department carries out the greatest number of electrophysiological operations in the country.

There is extensive experience in the ablation of arrhythmogenic foci in the pulmonary veins for the treatment of atrial fibrillation. It is the first department in Greece that has started performing these procedures. The most up-to-date anatomical mapping systems (CARTO and NAVEX) are used in combination with the conventional methods.

In the field of device implantation the Electrophysiology Unit is specialized in bifocal, monofocal and biventricular pacemakers’ and defibrillators’ implantations. The implantation of biventricular devices for the treatment of patients with heart failure started in the beginning of the millennia with great success. There has also, been important research which has been published in several international journals and has confirmed the superiority of biventricular pacing in the treatment of patients with heart failure.

The monitoring of patients with pacemakers and defibrillators consists one of the most methodical units in OCSC. The organized regular clinics of the implantable devices are staffed with specialized physicians and nurses and follow the know-how and the monitoring protocols of London Westminster Hospital.

The department is also specialized in the control of patients with syncopal episodes. In this context, besides the electrophysiological studies, tilt tests are also performed for the control of the patients with unexplained syncope. Research in this area has been followed by many publications; in fact, the use of clomipramine during tilting has been accepted by many foreign centers as a test drug during recumbency. There are also, transplants of continuous loop recorders (ILP) for diagnostic purposes in patients with syncope of unknown etiology.

The department is also specialized in non-invasive control with 24-hour rhythm recording (Holter rhythm) as well as the recording of the autonomic nervous system on patients with arrhythmogenic problems, patients with syncope of unknown cause, and sudden death. Moreover, the sensitivity of baroreceptors and the heart rate variability are studied and the volatility of peripheral resistance is evaluated by plethysmography.
