Abstract
An implantable medical device, implantable cardiac stimulation device, implantable defibrillator or pacemaker provides continuous monitoring of blood-glucose concentration in the blood of a patient. Blood-glucose concentration and blood-glucose concentration trends are calculated by measuring changes in the hematocrit of the patient. An external blood-glucose monitor may be used to provide blood-glucose calibration values to the implantable device to enhance accuracy of blood-glucose concentration values. The implantable device compares the blood-glucose concentration and/or concentration trends with acceptable limits and generates appropriate warning signals. The implantable device may optionally control one or more therapeutic devices to maintain blood-glucose concentration within an acceptable range. The enhanced control of blood-glucose concentration reduces the risk of arrhythmia and enhances the effectiveness of cardiac pacing and/or defibrillation.
