ABSTRACT:
In an electronic sphygmomanometer for a vehicle having a Korotkoff sound detecting circuit, a cuff pressure detecting circuit, a Korotkoff reference signal generator, a central processing unit for receiving the output of the Korotkoff sound detecting circuit, the output of the cuff pressure detecting circuit and the output of the Korotkoff reference signal generating and determining a systolic and diastolic blood pressure and a display unit for indicating the systolic and diastolic blood pressure, the electronic sphygmomanometer includes a cardioelectric potential detecting circuit having one-shot pulse generating circuit and the Korotkoff reference signal generator includes a flip-flop for receiving a cardioelectric potential synchronizing signal and pulse pressure variations signal so that the electronic sphygmomanometer mounted on the vehicle is not very much adversely affected by the vibration and noise.
