OBJECTIVE: To evaluate the dynamic RT (QRS apex-end of T wave) rate dependence in newborns. STUDY DESIGN: A Digital Holter ECG was acquired on day 15 in nine full-term and eight preterm infants.
In a recent article published in Npj Digital Medicine, researchers utilized electrocardiogram (ECG) data from a large retrospective cohort to extract various heart rate variability (HRV) measures.
