Abstract
Methods and apparatus for assessing cardiac risks in a specific patient. One embodiment of a method in accordance with the invention comprises providing heart rate activity of a specific patient including a windowed time series relating to heart rate variability during a heart rate test. This method further includes determining a frequency domain value based on energy values of frequency bands of the heart rate variability in the windowed time series, and/or determining an aggregate power for a frequency band of the windowed time series. This method further includes assessing the risk of a cardiac event based on the frequency value and/or the aggregate power.
