So, the RCG HRV analysis may be quite an adequate and perspective method of the actual cardiovascular status assessment during carrying out cardiac revascularization in CAD. HRV during CABGS has been shown to be effective in the definition of life-threatening arrhythmias during surgery, revealing different changes of the sinoatrial heart node (SN) deregulation during and after CABGS. Patients with diagnosed ACN need more careful preparation for revascularization surgery. Actual multiple deregulations of SN pacemaker activity testified to its adequacy to cardiac physiology of each stage of this cardiac operation, according to initial ischemic defeats and localization of cardiosurgical manipulations during CABGS. The study was based on the assumption that during cardiolovascular surgery intervention, the high-resolution analysis of sinoatrial node (SN) deregulations can be useful in an actual diagnosis of the intraoperative cardiovascular status Hainsworth (1995), Zhemaytite at al. (1982), Mironov (2002), Lakusic at al. (2009), Dao at al. (2010), Hugh at al. (1997), Kalisnik at al. (2007), Min at al. (2010), Brener at al. (2008), Kazemi at al. (2011), Ksela at al. (2009), Laitio at al. (2007), Carney at al. (2005). Earlier researches on this subject had no convincing results Zhemaytite at al. (1982). This, we assume, was connected to insufficient results at low sensitivity of the HRV registration and analysis, and also with humoral-metabolic influence on the autonomic regulation of the pacemaker activity of the SN ignorance Lakusic at al. (2009), Dao at al. (2010), Hugh at al. (1997), Kalisnik at al. (2007), Min at al. (2010), Brener at al. (2008), Kazemi at al. (2011), Ksela at al. (2009), Laitio at al. (2007), Carney at al. (2005). Innovative contemporaneous achievements in the HRV registration and analysis are especially important for identification of predictors and markers of the intra- and postoperative complications Zhemaytite at al. (1985), Kalisnik at al. (2007), Min at al. (2010), including life-threatening cardiac arrhythmias Zhemaytite at al. (1985), Dao at al. (2010), Brener at al. (2008), Kazemi at al. (2011). RCG data reflect a synaptic regulative level status and therefore can be quite precise. The RCG intra-surgery with HRV analysis through every 300 RR-intervals was studied in another program of continuous RCG-record monitoring on screen. In a retrospective analysis, the patients with HRV stabilization and
