[Relationship between human emotional status and parameters of central hemodynamics during physical and psychological...

Changes in central hemodynamics (CHD) to postural changes, psychoemotional stress (mental arithmetic subtraction test) and combined isometric and psychoemotional stress were studied in 21 healthy males aged 18-23, and correlation between CHD parameters and 23 psyhoemotional traits was determined. Negative correlation of the arterial pressure level with parametres of physical aggression, the total level of aggression, and rigidity, as well as its positive correlation with the excitation processes in cerebral cortex have been found. Cardiac output index just after postural loading and at the combined stress correlated with sense of fault. Heart rate at isometric loading correlated with the sense of fault, either. Thus, the arterial pressure is the parameter of CHD that correlates with the human psychoemotional status most closely.
