  • Patent number: 6011989
    Abstract: An electrocardiogram signal derived from electrocardiogram measuring means 1 and a pulse signal derived from pulse-wave measuring means 2 are applied to a CPU 30. The CPU 30 processes the cardiogram signal to detect a QRS wave signal, and processes the pulse signal to detect the amplitude of the pulse signal. The CPU 30 judges whether or not the QRS wave is caused by a ventricular premature contraction. If two QRS waves, not caused by ventricular premature contraction, occurs successively, and the CPU 30 judges if A0.times.k>A1. The CPU 30 judges that a supraventricular extrasystole is occurred. Here, A0 is an amplitude of the first QSR wave; A1 is an amplitude of the second QSR wave; and k is a preset value, 0<k<1.

  • Patent number: 4577976
    Abstract: A pair of metallic thin films are attached to opposite surfaces of a heat resistive thin film, and the heat flux through the heat resistive thin film is determined by measuring the temperature gradient therein while using the metallic thin films as resistance thermometer elements.
