An impedance monitor for discerning edema through evaluation of respiratory rate. Preferred embodiment includes edema monitor and trigger to initiate diagnostic reporting or corrective action when activated. Recording of Long Term Average and Short Term Average values for secondary edema measure based on DC signal level are described as are methods and apparatus for removing unwanted recurring noise.

[ What is claimed is:] [1.] An implantable edema monitoring device having:an impedance sensor for making impedance measurements in a living body into which said device is implanted, andmemory and evaluation circuitry means for monitoring said impedance measurements, and for generating a value representative of respiratory rate based on evaluation of said impedance measurements over time,edema value generator circuitry means for monitoring changes in said respiratory rate value, so as to generates an edema level value indicative of a measured value of edema in said living body based solely on said changes in said respiratory rate value.
