ABSTRACT:
An apparatus for simultaneously monitoring the heart rate of each of a plurality of subjects comprises a main circuit for transmitting a predetermined signal of predetermined frequency and duration and at predetermined time intervals to cause each of a plurality of remote subcircuits to transmit subcircuit identity data and heart rate data in predetermined timed sequence, a receiver for receiving remote subcircuit transmissions and producing an output representative of the heart rate of a subject and a plurality of remote subcircuits, each remote subciruit having a pulse monitoring device adapted to be secured to a subject for detecting and producing an output in response to a heart beat, and a detector for detecting the pulse monitoring device output and determining the number of the outputs which occur within a predetermined time interval, and being responsive to the main circuit predetermined signal for transmitting to the main circuit a signal representative of subcircuit identity data and the number of the detected heart beats.
