This case report presents the treatment of female patient G., aged 57, with a diagnosis "Atypical left atrial incisional flutter", came out after the initial procedure of radiofrequency ablation of the pulmonary veins due to the ectopic atrial tachycardia. The patient underwent a successful ablation of the left isthmus with the help of the three-dimensional nonfluoroscopic navigation system SJM EnSite Velocity. Dynamic follow-up showed complete freedom from paroxysmal tachycardia in the postoperative period. This observation shows the necessity of using such systems in routine practice in patients with complex heart rhythm disorders not only to accurately determine ectopic foci, but also to verify the damage zone during ablation, check the consistency of the bidirectional blockade, as well as construction of temporary activation card with the ability to visualize the conduction front before and after the procedure, which gives an accurate representation of the macromechanisms of reentry arrhythmias.
