| abstract | Electrical pulse width measuring apparatus wherein the presence of a pulse of unknown time duration is utilized to initiate generation of a reference pulse of known time duration. The reference pulse is generated by means including a monostable multivibrator together with a controlled driving circuit connected to the multivibrator timing capacitor. The time duration of the reference pulse accordingly is made linearly proportional to an input control variable such as a manually adjustable dial setting. The unknown and reference pulses are applied as inputs to a flip-flop circuit, the final state of which is determined by the pulse of longer time duration. An indicator coupled to the flip-flop circuit provides a visual indicator of the final state thereof. The apparatus can be used to measure or monitor a signal occuring in the body of a patient, such as the artifact pulse from an implanted cardiac pacemaker. The apparatus includes means to condition the artifact pulse and to generate a standardized pulse which accurately represents the width of the pacemaker pulse, and the apparatus further includes means for indicating when the width of the pacemaker pulse changes by a predetermined amount. |
