A simple device for measuring the momentary cardiac frequency (i.e. a value proportional t-r the length of the time interval between two cardiac contractions) is worked out using a capacitoo transducer consisting of two capacitors and an electron control circuit. The sequence of the charging, indication of the voltage and the discharge of the capacitors is… (More)
