A method and apparatus for monitoring ECG signals are described characterized in that an ECG signal wave is detected, filtered to pass only a frequency band within a range of about 25-300 Hz, and stored in a first storage device; and each successive ECG signal wave is then detected, similarly filtered, and stored in a second storage device. Each of the successive signal waves, when stored in the second storage device, is cross-correlated with the signal wave stored in the first storage device, and a determination is made whether the maximum cross-correlation coefficient exceeds a predetermined value. Each of the successive signal waves having a maximum cross-correlation coefficient exceeding the predetermined value is averaged with the waves stored in the first storage device following which it is stored in the first storage device in place of the signal wave previously stored therein, and is also displayed.
