A simple analog circuit is described which is capable of measuring on a beat‐to‐beat basis P‐R, R‐P, P‐P, and R‐R intervals during sinus rhythm and paroxysmal supra ventricular tachycardia. In addition the circuit will emit a pulse when the consecutively alternating P and R wave sequence is interrupted thereby signalling a trigger problem or a change in rhythm. The operation of the device requires proper P and R wave sensing and provides outputs which are linear over a range of rates which are applicable to the human heart.
