ABSTRACT:
A system and method of determining the status of an adverse cardiac condition of a medical patient based on circadian variation of one or more hemodynamic parameters are provided. In some embodiments, the system and method calculate a first average value of a series of first values during a first time period, a second average value of a series of second values during a second time period, and a difference between the first average value and the second average value. The method provides an indication of an adverse cardiac condition when the difference is less than a predetermined threshold.
