Abstract:
1. A method for use with an implantable medical device for distinguishing between hypoglycemia and hyperglycemia within a patient in which the device is implanted, the method comprising: tracking with said implantable medical device, amplitude-based parameters within electrical cardiac signals over time corresponding to amplitudes of atrial depolarizations, ventricular depolarizations and ventricular repolarizations; detecting with said implantable medical device, hyperglycemia upon detection of an increase in atrial depolarization amplitudes, an increase in ventricular depolarization amplitudes and a lack of significant change in ventricular repolarization amplitudes; and detecting with said implantable medical device, hypoglycemia upon detection of a lack of significant change in atrial depolarization amplitudes, an increase in ventricular depolarization amplitudes and an increase in ventricular repolarization amplitudes.
