ELECTROCARDIOGRAM APPARATUS HAVING ARRHYTHMIA DETECTING FUNCTION

摘要

PURPOSE: An electrocardiogram apparatus having anarrhythmia detecting function is provided to improve the simplicity of a disease diagnosis related to a heart by generating an alarm when an electrocardiogram signal having an abnormal waveform is detected. CONSTITUTION: An analog/digital converter(100) converts an analog electrocardiogram signal into a digital electrocardiogram signal. A digital signal processor(110) eliminates noise from the digital electrocardiogram signal converted by the analog/digital converter(100). A linear prediction filter(120) inputs the digital electrocardiogram signal without the noise to predict a present inputted signal by a previous inputted signal and generates an error signal between the predicted value and the present inputted signal. A signal analyzer(130) detects an arrhythmia signal by the digital electrocardiogram signal without the noise and the error signal generated in the linear prediction filter(120) and generates information required for the diagnosis.
