Abstract:
A system for simultaneous monitoring of a plurality of individuals comprising:an individual physiological data logger (IPDL) for each individual for measuring and storing heart beat data, the IPDL including:an electro-cardiogram (ECG) measuring device for providing heart beat data;an extended memory for storing said measured heart beat data;a synchronization element;a micro-controller including a synchronization element controlling circuit; andRF transceiver apparatus;a central interface unit selectably couplable by radio telemetry communication to each IPDL for transmitting thereto a plurality of commands and for receiving therefrom said heart beat data; anda computer coupled to said central interface unit for providing commands for each said IPDL, for performance of an individual bench test for deriving an individual conversion coefficient of heart beats cost per unit of mechanical work, and for monitoring and analyzing, in real time, said heart beat data, utilizing said individual coefficient of heart beats cost per unit of mechanical work, of each of the plurality of individuals, wherein said computer scans said heart beat identification data during analysis and commands said central interface unit to request re-transmission of any missing heart beat data.
