ABSTRACT:
A small portable-type apparatus for checking pulse or heart rate of a person engaged in exercise. Therefore, the apparatus according to the present invention can be used as a pulsimeter or a cardiometer according to the state of a person in motion. The apparatus is provided with a heart sensor having a plurality of cone-shaped conductive rubber electrodes to differentially detect an electrocardiowave voltage signal generated from three different places near the heart and a pulse sensor having a matching infrared-ray emitting diode and infrared-ray receiving phototransistor to detect the light reflected from the blood flowing through capillary vessels under the finger pad. The apparatus additionally functions as a stopwatch or a timer as selected by a mode-selector switch.
