Abstract
A method of assessing cardiac ischemia in a subject to provide a measure of cardiac or cardiovascular health in that subject is described herein. The method comprises the steps of: (a) collecting a first RR-interval data set from said subject during a stage of gradually increasing heart rate up to a predetermined heart rate of at least 130 beats per minute; (b) collecting a second RR-interval data set from said subject during a stage of gradually decreasing heart rate; (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.
