HeartLight Pulse Study: Evaluation of Heart Rate Using an Electronic Stethoscope and Pre Placed ECG in the Delivery Room

Inclusion Criteria: * All must have written informed consent from the participant's mother * Phase 1: Any neonate requiring NICU admission and routine monitoring with ECG. * Phase 2: Preterm infants ≤32 weeks gestation delivered into a plastic bag/wrap Exclusion Criteria: * Phase 1: Infants undergoing comfort care (palliative care). Infants deemed too sick, as assessed by the clinical team caring for them, to tolerate additional procedures. This is unusual but would normally include infants who become more unstable with increased handling * Phase 2: Infants \>32 weeks gestation Infants where resuscitation is unlikely to be instigated (eg. known lethal condition)
