  • Publication number: 20200229728
    Abstract: An R wave peak detection method uses the periodicity of an electrocardiogram signal, in which expected R wave peaks are detected from an electrocardiogram signal, and a time difference between the expected R wave peaks that are detected is calculated in order to output, as actual R wave peaks, only expected R wave peaks that are greater than a threshold time difference, thereby avoiding a case in which the R wave peaks are erroneously detected from an non-ideal electrocardiogram signal.
