The localization of the substrate of atrial tachycardia is primarily associated with the following areas: crista terminalis, interatrial septum, annulus of mitral and tricuspid valves, right and left atrial appendage, ostium of pulmonary veins and coronary sinus (CS) ostium [2,3,4,5,6,7,8]
For some patients, the standard approach does not guarantee the success and safety of treatment for arrhythmia. When it comes to the localization of the tachycardia substrate in the anterior region of the interatrial septum, where the anatomic al proximity to the compact part of the atrioventricular (AV) joint makes it difficult to place optimally the ablation catheter, since radiofrequency (RF) exposure in this area has a high risk of disruption of AV conduction

After repeated arrhythmia substrate was performed in more than one of ablation, in the patient there were remained attacks of frethese areas, for example, combined procedures were done quent rhythmic heartbeat (up to 5-6 times per day) with a in the region of crista terminalis and atrial septum, as well ventricular contraction rate from 150 to 200 beats/min and as in crista terminalis and cavotricuspid isthmus. Upon admission on ECG (Fig.1), there is sinus originating from interatrial septum, 14 patients under- rhythm with heart rate (HR) 85 beats/min, frequent APB.
