Abstract
An apparatus for detecting a high frequency artifact contained in an electrocardiogram signal is disclosed, which enables the presence of the high frequency artifact to be detected with a high precision by extracting high frequency components having a frequency and amplitude equal to or more than a predetermined value within a predetermined time interval of the input electrocardiogram signal by converting the high frequency components to pulses, by counting the pulses, and by comparing the counted pulses with the predetermined value. This apparatus is used in connection with, for example, an electrocardiograph, an electrocardiogram analyzer, and the like, and enables precise discrimination between an abnormal electrocardiogram waveform and the high frequency artifact.
