Techniques are described for detecting ischemia, hypoglycemia or hyperglycemia based on intracardiac electrogram (IEGM) signals. Ischemia is detected based on a shortening of the interval between the QRS complex and the end of a T-wave (QTmax), alone or in combination with a change in ST segment elevation....http://www.google.ca/patents/US20060167518?utm_source=gb-gplus-sharePatent US20060167518 - System and method for distinguishing among cardiac ischemia, hypoglycemia and hyperglycemia using an implantable medical device
