Methods of mutual analysis of rhythmocardiogram and pneumatogram signals to evaluate of body adaptation reserves

摘要

The paper deals with the task of identifying the real “respiratory” component of the rhythmocardiogram signal when estimating parameters of heart rate variability. Different methods for formation criterion of synchronization between the cardiovascular and respiratory systems are analyzed. The analysis of possible sources of error in estimation of synchronization criterion with the different methods is made and experimental studies showing the way forward optimal development of methodology for control of this trait are prepared. The method of forming a criterion of synchronization based on the Fechner's correlation coefficient evaluation is proposed. The stability of the developed method to the influence of various artifacts is evaluated. Conclusions about the effectiveness of the method developed are made.
