Disclosed is the patent of a one-shot multivibrator of simplified and inexpensive construction which produces a constant width output pulse and which once triggered is not affected by additional trigger pulses until after the timing cycle is completed. A charged capacitor and resistor maintain a pair of transistors conducting and the transistors change state when current flow is diverted from them through a third transistor in response to a triggering signal. The multivibrator output is connected by a negative feedback lead to the third transistor. Also disclosed is a rate monitoring portion of an electrical heart monitor incorporating the multivibrator.
