Removes the pace impulse signal from manner and the ECG wave signal which remove the pace impulse signal from the ECG wave signal the device

摘要

Apparatus for effectively eliminating pace pulses from an ECG wave without introducing distortion comprising means for comparing the slope of the ECG wave with a threshold slope derived from the wave that is greater than the maximum slope produced in the wave by heart action and substituting values for a portion of the wave between first and second points on either side of the place in the wave where its slope exceeds the threshold value, the substituted values being interpolations of the value of the ECG wave occurring at said points. In a preferred embodiment means are provided for preventing the substitution from occurring unless a pace pulse is detected within a given distance of the said place in the ECG wave and means are also provided for setting said first point at a place in the ECG wave that occurs prior to a tail that precedes it.
