Abstract
An ECG signal processing system which removes the CPR-induced artifact from measured ECG signals obtained during the administration of CPR.
Claims10
A system for producing a processed ECG signal, said system an ECG signal processor for processing a measured ECG signal from a patient undergoing CPR, said signal processor comprising:
- a first input for receiving a motion signal indicative of the displacement of a CPR recipient's chest during the 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 measured 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:
- a accelerometer-based displacement detector for providing a signal indicative of the displacement of the CPR recipients chest to the first input.
