Abstract: | The ratio of the period of cardiac cycle to the period of vessel autofluctuations is constant in healthy resting humans. This ratio constitutes 1.309 +/- 0.068. The same correlation is observed between the duration of the pneumo-cycle and the period of respiratory arrhythmia. At working and post-constriction hyperemia, there is a resonance in cardiac-respiratory-hemodynamic system that synchronizes the fluctuation processes of its constituent elements and increases the RVG amplitude. The data obtained have been discussed. |
