ABSTRACT:
In general, the invention is directed to monitoring fluid retention that may accompany congestive heart failure and pulmonary edema. A medical device, such as an implanted pacemaker or an external defibrillator, senses electrical signals associated with the periodic depolarization and re-polarization of a heart. The device processes the electrical signals to obtain one or more “cardiac parameters,” which reflect pulmonary edema. By monitoring the cardiac parameters, the device monitors pulmonary edema. Cardiac parameters comprise the amplitude of the QRS complex, the integral of the QRS complex, or the integral of the QRST segment and the like. When the device detects fluid buildup, the device may respond by taking remedial action and/or generating an alert.
