title: [Variation cardiac intervalometry -- a component of neurophysiological monitoring].
abstract: The course of intraoperative period is retrospectively analyzed in patients operated on for bulky formations of the brain. Mathematical analysis of cardiac rhythm structure, performed using an original method within the framework of operation monitoring, detected early signs of disorders in adaptation systems, indicative of insufficient anesthesia and overrun physiological permissiveness during the main stages of operation. The results of the study extend our notions on the potentialities of traditional monitoring and improve the efficiency of neuroanesthesiological support and choice of surgical strategy.
