1. A pulse rate monitor for analyzing two concurrent pulse sequences, comprisinga first detector for a first sequence of pulses;
- an electronic histogram unit having an input and a plurality of output channels corresponding to predetermined pulse spacings;
a set of first counters and a set of second counters each having a data input and a plurality of data outputs and each being provided with display means, said first and second counters being assigned to respective output channels of said histogram unit;
a set of dividers connected between the outputs of said first and second counters to produce quotients of counts of the latter, each of said dividers being provided with display means;
a clock pulse generator;
a second detector for a second sequence of pulses;
switching means having a first switching position in which said first detector is connected to the input of said histogram unit, the inputs of said first counters are connected respectively to said output channels and said second counters being connected in series with said generator, and a second switching position in which said first detector is connected to each input of said first counters, said second detector is connected to the input of said histogram unit, and the inputs of said second counters are connected to an output of said clock pulse generator; and
control means for controlling the connection between said first detector to said first counters, and the connection between said clock pulse generator and said second counters to activate in the second position of said switching means, those first and second counters which pertain to an active output channel of said histogram unit.

Abstract
A pulse rate monitor has an electronic histogram unit, an averaging unit including a clock generator and two sets of counters with a set of dividers therebetween. Each set of counters and dividers is provided with display devices. Switching and controlling elements are provided to interconnect respective sets and units of the monitor for various modes of operation.
