The ablation and mapping catheter dedicated to treatments in electrocardiology and ablation of cardiac arrhythmias with the possibility of visualisation includes a distal tip, diagnostic rings, a main tube, a guiding handgrip, and an electrical connector for a generator through which the diagnostic rings and a distal ring are connected to a system for three-dimensional electroanatomical mapping. The catheter includes at least 8 (up to 14) diagnostic rings, wherein 4 diagnostic distal rings are connected to one generator and through it to the system for three-dimensional electroanatomical mapping and to an electrophysiological system, and subsequent 4 (up to 10) diagnostic proximal rings are connected to a second generator and/or to the system for three-dimensional electroanatomical mapping and to the electrophysiological system.
