ABSTRACT:
A method of determining an impedance of at least one lung of a patient having an implanted pacemaker that comprises first and second leads and a case, the method comprising:a) using the leads and the case to acquire at least a first and a second impedance measurement responsive to impedance of the patient's chest that are at least partially independent; andb) using the impedance measurements to determine the impedance of at least one of the lungs substantially independently of impedance of the other lung.
