ABSTRACT:
A method for detecting a QRS complex of an ECG is provided. The method includes the steps of inputting an ECG signal, setting a first threshold value based on a peak value of a QRS complex of the ECG signal, setting a second threshold value by estimating a noise level proprotional to the amount of noise included in the ECG signal comparing the first threshold value with the second threshold value, deeming a larger one of the first and second threshold values to be a third threshold value for detecting the QRS complex, detecting the QRS complex by using the threshold value for detecting the QRS complex, and outputting a synchronous signal synchronized with the detected QRS complex.
