FIELD: medicine.
SUBSTANCE: method involves setting electrodes in left and right atrium, right ventricle and His bundle positions. Superficial electrocardiogram, endocardial hisogram and epicardial ventriculogram are recorded. Programmed electrostimulation is carried out via atrial electrode. Recorded interval growth jumps being found greater than 40 ms with extrastimulus delay drop reaching 10 ms, atrioventricular node conduction switch to the other channel is documented. Two or more switches taking place, paroxysmal ectopic atrioventricular tachycardia occurrence is to be predicted.
EFFECT: high accuracy of early stage prognosis.
