Recorded were: cardiotachogram (CTG as RR interval) and T-wave amplitude from ECG, ear-lobe photo-plethysmogram, digital impedance rheogram, thermistor pneumogram (PNG). Heart rate (HR) and systolic pressure (SP) data were treated using the Fourier analysis on a M118B microcomputer. Preliminary data-exploration, reported in a previous paper, has verified the capability of the Fourier spectrum to spot in short quasistationary data-series known marks of single interventions and has pointed to the amphotrop nature of SLI and FI maneuvers. Present work approaches the same data from the point of view of the competition between various regulatory menus under combined interventions. The \"cortico-cardiac reflex\"--HR stabilizing under mental loading versus rest based upon balanced reduction in both respiratory and vasomotor sinus arrhythmia (RSA and VSA, respectively)--appeared now as a middle size actor upon medullary areas; it is overridden, yet not put to silence by the powerful orthostatic reflex; it is comparable (SLI) or major (FI) vis-a-vis of synergic vagal reflexes whose more easily approachable mechanisms could offer it meaningful models.
