Abstract

The most important step for the operator to perform a successful radiofrequency ablation procedure for the treatment of cardiac tachyarrhythmias is to accurately identify the origin of and localize the arrhythmia focus and to determine the sequence of electrical activity. Intracardiac mapping techniques came a long distance from single catheter recordings to three dimensional voltage and morphology reconstructing systems. The aim of this review is to summarize the benefits and disadvantages of the existing cardiac mapping systems.
