METHOD FOR PREDICTING ATRIOVENTRICULAR HEART BLOCKS AFTER RADICAL CARDIOSURGICAL HEART TROUBLE CORRECTION IN EARLY AGE CHILDREN Russian patent published in 2005 - IPC

FIELD: medicine.

SUBSTANCE: method involves carrying out epicardial electrophysical study during operation on heart after having done the thoracotomy and exposing pericardium cavity. Programmed electrostimulation with continuously reducing extrastimulus delay is performed on the left atrium via an electrode. Relative refraction period of the right pedicle of His bundle, effective refraction period of the right atrium and effective refraction period of the atrioventricular node is found. The effective refraction period of the atrioventricular node being greater than the effective refraction period of the right atrium, postoperative atrioventricular heart block risk at the level of atrioventricular node is to be predicted. The relative refraction period of the right pedicle of His bundle value being greater than value being greater than the effective refraction period of the atrioventricular node, postoperative atrioventricular heart block risk at the level of His bundle and its branches is to be predicted.

EFFECT: high accuracy of prognosis.
