Supraventricular arrhythmias, electrophysiological study, diagnosis

In order for the best exploitation of the newer therapeutic possibilities, the ac­curate knowledge of the electrophysiological background of the arrhythmias is necessary. The study of the electrophysiological properties of the several myocardial areas (refractory periods, con­duction times) in association with the programmed stimulation of the atria and ventricles, the obser­vation during tachycardia paroxysm and the re­sponse to acute administration of antiarrhythmic drugs comprise effective diagnostic methods con­ducted in the electrophysiology laboratory. Α number of catheter-electrodes is introduced into the heart; pacing, programmed extrastimulus de­livery and myocardium electrical signal recordings are performed with them. Several electrophysio­logical properties detected by the proper tests discriminate between forms of automaticity and reentry in pathogenesis of supraventricular tachy­cardias. The most important are the atrioventricular and atrioventricular nodal reentry tachycardias, since ablation techniques are increasingly used in their treatment.
