A method of assessing cardiac ischemia in a subject to provide a measure of cardiovascular health in that subject is described. In general, the method comprises the steps of: (a) collecting a first RR-interval data set from the subject during a stage of gradually increasing heart rate; (b) collecting a second RR-interval data set from the subject during a stage of gradually decreasing heart rate (e.g., after an abrupt stop in exercise; during a stage of gradually decreasing exercise load; etc.); (c) separating fluctuations from a slow trend in the first RR-interval data set; (d) separating fluctuations from a slow trend in the second RR-interval data set; (e) comparing the fluctuations of the first RR-interval data set to the fluctuations of the second RR-interval data set to determine a difference between the fluctuation data sets; and (f) generating from the comparison of step (e) a measure of cardiac ischemia during stimulation in the subject, wherein a greater difference between the first and second data sets indicates greater cardiac ischemia and lesser cardiac or cardiovascular health in the subject.

Exercise test scheme and calculation method for cardiopulmonary function
The invention discloses an exercise test scheme and a calculation method for a cardiopulmonary function, and belongs to the field of health assessment. A maximal oxygen uptake is a key assessment index of aerobic exercise ability and a core index to reflect an exercise cardiopulmonary function; moreover, in all-cause death attribution analysis, a low cardiopulmonary function is an all-cause death factor ranked first and therefore the assessment on the exercise cardiopulmonary function is very necessary; however, to directly test an oxygen uptake, a very precise instrument is required; and the equipment is expensive and therefore cannot be applied in the field of public fitness. In the method, by researching the shortages of a previous method in depth, an incremental load scheme that measures the maximal oxygen uptake under a secondary high intensity exercise is formulated; on the basis of observing a heart rate reaction after a small-load (25W) excise, a load at a second level is determined; and meanwhile, in a stage of an open test, effective data can be guaranteed to be collected; and based on this, according to a result obtained by the test, a new calculation method for the maximal oxygen uptake is provided; and the method of multipoint regression is adopted, so the error caused by heart rate fluctuation in previous two-point calculation is greatly reduced.
