Abstract
A medical device obtains an oscillometric measurement associated with a patient'"'"'s non-invasive blood pressure reading. The device determines a stability measure for at least one pair of pulses included in the oscillometric measurement, compares the stability measure to a threshold, and excludes the pair of pulses from an evaluation of heart beat variation when the stability measure fails to meet the threshold.
