1 Overnight pattern of heart rate before and after the appearance of an adult-like night time body temperature pattern. Overnight pattern of heart rate before and after the appearance of an adult-like night time body temperature pattern. The mean heart rate of 119 babies is plotted at half hourly intervals from bedtime for two weeks before and three weeks after an adult-like night time body temperature pattern first appeared. Heart rate fell significantly between two weeks and one week before (t = 4.98; 118 df; p < 0.001), and then fell significantly again between the week before and the weeks of attainment of the adult-like pattern (t = 4.40; 118 df; p < 0.001).
