<p>The implantable device for long term monitoring of congestive heart failure employs a signal generator, such as within a pacemaker, to generate an electrical signal which is monitored to obtain a single or dual frequency measurement that can independently measure systemic venous and pulmonary (lung) impedance. The device is able to detect changes in resistance to a flow of current in the systemic venous system and changes in impedance to a flow of current through a lung to thereby indicate separate detection of systemic venous and pulmonary congestion.</p> |
