  • Patent number: 11433242
    Abstract: A pulse discrimination device is configured to receive electrical signals from a plurality of positions of a living body to which a pacing device for outputting a pacing pulse to cause a heart to beat is attached, and is configured to discriminate the pacing pulse included in the electrical signals. The pulse discrimination device includes: a differential processor configured to calculate a difference of the electrical signals received from the plurality of positions, a sum processor configured to calculate a sum of the electrical signals received from the plurality of positions, and a pulse discrimination unit configured to discriminate the pacing pulse included in the electrical signals based on the difference obtained by the differential processor and the sum obtained by the sum processor.

  • Publication number: 20200093391
    Abstract: A pulse discrimination device is configured to receive an electrical signal from a living body in which a functional pulse propagates at a predetermined time interval, and is configured to discriminate between the functional pulse and a noise pulse which are included in the electrical signal. The pulse discrimination device includes: a pulse detector configured to sequentially detect an electrical pulse included in the electrical signal based on variation in an intensity of the electrical signal received from the living body; and a pulse discrimination unit configured to determine whether the electrical pulse detected by the pulse detector is the functional pulse or the noise pulse based on a detection interval of the electrical pulse detected by the pulse detector and a pulse time predetermined based on the predetermined time interval.
