First Claim
Patent Images
1. A method for treating cardiovascular disease in a medical patient, the method comprising:
- determining a thoracic impedance between a housing and an electrode, wherein the housing is located in the patient and wherein the electrode is located in the thoracic cavity of the patient;
determining the patient'"'"'s spatial orientation;
communicating the thoracic impedance and spatial orientation to a signal processing apparatus;
operating the signal processing apparatus to generate a signal indicative of an appropriate therapeutic treatment to the patient,wherein the signal is based at least in part on the thoracic impedance communicated to the signal processing apparatus and the patient'"'"'s spatial orientation andcommunicating the signal to the patient, wherein the signal comprises an instruction to the patient.

Abstract
A system for detecting and treating congestive heart failure includes an implantable module, such as a pacemaker, and a patient advisory module. The system is configured to measure thoracic impedance and to provide the patient with instructions in order to improve the accuracy of the thoracic impedance measurement as well as treating symptoms of congestive heart failure.
