Claim One:
1. A method of assessing cardiac ischemia in a subject to provide a measure of cardiac or cardiovascular health in that subject, said method comprising the steps of: (a) collecting a first RR-interval data set from said subject during a stage of gradually increasing heart rate, said heart rate being gradually increased by increasing the exercise load of said subject in response to actual heart rate data collected from concurrent monitoring of said subject; (b) collecting a second RR-interval data set from said subject during a stage of gradually decreasing heart rate, said heart rate being gradually decreased by decreasing the exercise load of said subject in response to actual heart rate data collected from concurrent monitoring of said subject; (c) comparing said first RR-interval data set to said second RR-interval data set to determine the difference between said data sets; and (d) generating from said comparison of step (c) a measure of cardiac ischemia during stimulation in said subject, wherein a greater difference between said first and second data sets indicates greater cardiac ischemia and lesser cardiac or cardiovascular health in said subject.
