Abstract
According to an aspect, a method for determining an augmented vital sign, such as heart rate or heart rate variability, includes obtaining signals from a patient when the patient is both active and inactive. An activity signal is generated from the first signal, and a physiological signal is generated from the second signal. An activity weight factor is calculated from the activity signal, and a vital sign signal is calculated from the physiological signal. A mapping from the activity signal to the vital sign aids the determination of the vital sign through a motion period. The augmented vital sign is a result of the combination of first and second values, including the product of the activity weight factor and an activity derived vital sign, and the product of the vital sign signal and the activity weight factor less than one.
