Abstract
The clinical examination of the cardiovascular systems efficiency based on methods of control theory demands favourable input signals and suitable response characteristics. In this paper by means of modelling it was intended to find aspects, which should allow to evaluate several test methods with regard to their correspondence to specific claims. A control model used for this purpose represents the baroceptor control of systemic arterial pressure by physical workload. Its alterations were considered in step, stair, ramp, and sinusoidal form. According to a judgement founded on theoretical and practical aspects, the aperiodic input changes prove to be advantageous. Especially the ramp test function seems to be suitable for selection of output components issuing from physical and mental parts of work-load.
