摘要
A method and apparatus for monitoring respiration in a patient sense a cardiac electrical signal and detect signal peaks from the cardiac electrical signal. A peak amplitude waveform is generated from the signal peaks. a first derivative of the peak amplitude waveform is computed. Inspiration pulses are derived from the first derivative signal, and a respiration metric can be computed using the inspiration pulses derived from the cardiac electrical signal.
