We aimed to independently determine whether respiratory support with a facemask is associated with a decrease in heart rate (HR) in some late-preterm and term infants. Methods: Secondary analysis of data from infants born at \u226532+0 weeks of gestation at 2 perinatal centres in Melbourne, Australia. Change in HR up to 120 s after facemask placement, measured using 3-lead electrocardiography, was assessed every 3 s until 60 s and every 5 s thereafter from video recordings. Results: In the 15 s after facemask placement, 10\/68 (15%) infants had a decrease in mean HR by &amp;gt;10 beats per minute (bpm) compared with their individual baseline mean HR in the 15 s before facemask placement. In 4 (6%) infants, HR decreased to &amp;lt;100 bpm. Nine out of 68 (13%) infants had an increase in mean HR by &amp;gt;10 bpm; 7 of these infants had a baseline HR &amp;lt;120 bpm. In univariable comparisons, the following characteristics were found not to be risk factors for a decrease in HR by &amp;gt;10 bpm: prematurity; type of respiratory support; hypoxaemia; early cord clamping; mode of birth; HR &amp;lt;120 bpm before mask placement. Six out of 63 infants (10%) who had HR \u2265120 bpm after facemask placement had a late decrease in HR to &amp;lt;100 bpm between 30 and 120 s after facemask placement. Conclusion: Facemask respiratory support at birth is temporally associated with a decrease in HR in a subset of late-preterm and term infants.
