System, method, and apparatus for combining information from an implanted device with information from a patient monitoring apparatus
First Claim
1. A computer-implemented method of detecting an impending decompensation of heart failure in a patient, the method comprising:
- receiving transthoracic impedance data measured by a cardiac rhythm management device implanted in the patient;
obtaining a weight measurement of the patient; and
detecting impending decompensation of acute heart failure, based at least in part upon the weight measurement and the transthoracic impedance data received from the cardiac rhythm management device.

Abstract
A data set is generated by an implanted medical device, during operation of the device. The data set includes data characterizing various physiological states of the patient. The data set is communicated from the device to a patient monitoring apparatus. The patient monitoring apparatus develops its own data set by posing questions to the patient, and optionally by measuring a physiological parameter of the patient, such as weight. The two data sets are combined and are analyzed to determine medical information concerning the patient, such as impending decompensation of heart failure.
