A recent study suggests that a small equation, combining steps taken and resting heart rate data from your smartwatch, might significantly improve heart health monitoring. Researchers at Northwestern University’s Feinberg School of Medicine, in a study published in the Journal of the American Heart Association, propose a new metric: the daily heart rate per step (DHRPS). This ratio, achieved by dividing the average resting heart rate by the average daily steps, can indicate how efficiently one’s heart is functioning.
