FIELD: medicine.
SUBSTANCE: pluripolar electrode is pulled to a coronary sine using endovscular access and bipolar electrogrammes are registered. Thus during an atrial electrical stimulation potential of a left ventricle V is analysed, during a ventricular electrical stimulation or orthodromic tachycardia potential of the left auricle A is analysed, two interfacing electrogrammes are defined, where there was a change of polarity of the specified potentials from "+" to "-", or on the contrary and a site between the poles from where the given electrogrammes are registered. Consider as the location of an additional spending way where make radio-frequency ablation.
EFFECT: increase of mapping accuracy of left-sided additional pathways at patients with the WPW syndrome.
