Overview

Rapid development and clinical introduction of 3D techniques of intracardial mapping significantly extended the possibilities of catheter ablation therapy of dysrhythmias. Contemporary imaging techniques allow precise determination of the source and the way of propagation of dysrhythmia in myocardium, which is an evitable condition of a successful ablation therapy. Although the fluoroscopic image during electrophysiologic examination allows continuous check of the position of catheters in the heart, due to its low resolution it remains just rough estimation of their real position. The objective of the authors of this lucid work was to give a brief characteristic of the basic principles of the activity of 3D mapping systems used nowadays and to approximate their significance and advantages for ablation therapy of individual dysrhythmias in clinical practice.

Key words:
ventricular and atrial dysrhythmias – non fluoroscopic 3D mapping techniques – radio-frequency catheter ablation
