1. A method for automatically determining ischemia detection parameters, comprising: obtaining a baseline trace indicative of a cardiac behavior; locating one of an R wave marker and a V wave marker in the baseline trace; analyzing the baseline trace to identify slope changes between points in the baseline trace; identifying a start point and end point in the baseline trace following the R wave or V wave marker as a function of the slope changes; determining an ischemia detection window based on the start and end points within the baseline trace, the baseline trace including a baseline segment within the ischemia detection window; and automatically determining a fiducial point by locating a fiducial point that yields a desired relation between the baseline segment and a new segment trace within the ischemia detection window, the ischemia detection window and fiducial point constituting ischemia detection parameters.
