A medical measuring device or system (10) includes at least one measuring apparatus (12, 14). Each measuring apparatus, in turn, has at least one sensor (16, 18) for generating a measuring signal representing a sensed physiological parameter, e.g. ECG signals, of a patient (20, 22). The measuring apparatuses (12, 14) incorporate the measuring signal into a carrier signal which is transmitted a wireless communication route (24, 26) to a centrally located data detection device (24) which displays graphs (42) or numerical values (40) representing the sensed physiological parameters. The at least one measuring apparatus (12, 14) signals the quality of the measuring signals to a wearing patient (20) via an LED (32, 34) or loudspeaker (28, 30).
