The normal conductance of an electrical impulse in the heart from the sinus node to the atria, and then through the atrioventricular node to the ventricles ensures that the contraction of the heart muscle occurs in a synchronized and organized manner. Abnormal electrical impulses in the heart result in asynchronous muscle contraction and unorganized work, reducing the efficiency of the pumping function of the heart. One of the most recognized methods of treatment for arrhythmias today is radiofrequency ablation of arrhythmogenic foci. One of the most frequently troubling questions of catheter ablation safety in case of cardiac arrhythmias is the risk of developing certain complications. The development of complications may depend on several factors, such as imaging technology, the experience of the surgeon. Minimizing the amount of ablation time and ensuring accurate tissue exposure can reduce these complications. Therefore, accurate identification and mapping of arrhythmic foci is important. After identifying these lesions, a more accurate ablation can be performed to free the patient from arrhythmia. A more recognized option is the electroanatomical mapping technology, which allows you to build a threedimensional geometry of the heart chambers, as well as a real-time arrhythmia distribution map. In addition, a wide variety of catheter types can be used in combination with electroanatomical imaging systems. The navigation system, using multi-pole catheters, shows where the ablation catheter is located, and makes it possible to accurately reach the target site with an ablation catheter and facilitates the ablation procedure itself. Multi-pole electrodes make it possible to register high-resolution signals from large anatomical surfaces in one motion. They can also adapt to the anatomical shape and size of certain areas of the heart, thereby ensuring accurate localization of the anatomical structures and the arrhythmogenic focus. For electroanatomical mapping today use round or spiral multi-pole catheters, multi-pole catheters in the form of a “basket”, multi-pole catheters in the form of a “star”, etc. Multi-pole new generation catheters are safe and effective. When using them, a high efficiency of the ablation procedure is noted (up to 100%). It is recommended to use new generation catheters because of their ability to identify an arrhythmogenic focus with a decrease in arrhythmia search time, detection and elimination of breaks after ablation, as well as a reduction in fluoroscopy time, which is very important not only for the surgeon, but also for the patient.
