Abstract
A pulsimeter for a vehicle comprises electrodes and an electronic unit for measuring heart pulsation rate of a vehicle driver. The electrodes are provided on a steering wheel assembly of a vehicle so that, when the driver touches the electrodes with his hands, electrical potentials corresponding to the muscular activity of the driver's heart are picked up. The electronic unit differentially amplifies the electrical potentials and the interval of time between pulsation signals successively produced by the differential amplification is measured to obtain the driver's pulsation rate. The pulsation rate may be used for display or for some other purposes.
