Abstract:
A method of producing a model EMG signal from a measured EMG signal, wherein the measured EMG signal includes a patient's EMG signal and an ECG signal, the method comprising the steps of:(a) processing a measured EMG signal to produce a logic signal that is (1) in a first binary state responsive to an absence of a P wave, a QRS complex and a T wave in a measured EMG signal and (2) in a second binary state responsive to a presence of at least one of the P wave, the QRS complex, and the T wave in the measured EMG signal; (b) processing the measured EMG signal to produce a current first envelope signal; and (c) producing a model EMG signal as a function of (1) the current first envelope signal responsive to the logic signal being in the first binary state and (2) a signal other than the current first envelope signal responsive to the logic signal being in the second binary state.
