Abstract
A method for operating an implantable medical device includes determining the difference of the absolute value of the voltage of a test QRS complex and the voltage of a baseline QRS template at a plurality of corresponding sample points and detecting ischemia if the sum of the differences at the plurality of sample points is greater than an ischemia detection threshold.
