Abstract
For suppressing cardiovascular artifact from a respiration signal derived from a patient's transthoracic impedance, an adaptive filtering device determines the patient's heart rate, converts the respiration signal from an analog to digital representation at a rate proportional to the heart rate, and then filters the digital respiration signal such that that portion of the respiration signal having a frequency content at or above the heart rate is most greatly attenuated.
