The statistical distributions of heart rate (HR) and heart period (HP) measures were compared for 10 adults. Kolmogorov‐Smirnov indices of fit and specific indices of skewness and kurtosis were applied to a 40‐min sample of baseline heart beats. Neither individual HR nor HP distributions were consistently normally distributed. Over the sample, HP distribution indices were not significantly different from normal although HR distribution indices were. The use of HP in measuring cardiac evoked responses is advocated.
