Patent ID: 8666480

Claim:
A system for producing a processed ECG signal, said system including an ECG signal processor for processing a measured ECG signal from a patient undergoing cardiopulmonary resuscitation (CPR), said signal processor comprising: a first input for receiving a motion signal indicative of a displacement of a CPR recipient's chest during administration of CPR by a rescuer to the CPR recipient; a second input for receiving a measured ECG signal during the administration of CPR; a CPR-induced artifact identifier for receiving said motion signal and said measured ECG signal and identifying a CPR-induced artifact contained in said measured ECG signal; and a CPR-induced artifact remover for producing a processed ECG signal by removing said CPR-induced artifact from said measured ECG signal; electrodes for detecting the measured ECG signal; and said system further comprising: an accelerometer-based displacement detector for providing a signal indicative of the displacement of the CPR recipient's chest to the first input.
