range of heart rate variation during variation of mean arterial blood pressure +
This calculated measurement is the range of change in heart rate (the number of contractions of the cardiac ventricles per unit of time) relative to the change in mean arterial blood pressure (the average force the blood exerts on an artery wall) over time and/or in response to a change in conditions.
