May favor heart rate in infant studies; leaves open optimal measure selection for adult cardiovascular research.
For statistical modeling in infants, heart rate is a preferable measure to heart period due to better normality and variance homogeneity.
Frances K. Graham (1978) reported a review. Heart rate measure vs. Heart period measure was evaluated on Normality of distributions and homogeneity of variance. Heart rate measures are more nearly normally distributed and homogeneous in variance than heart period measures in infants, whereas neither is preferred in adults.
