Why the study?
Does heart rate variability correlate with QTc interval in newborns?
Does heart rate variability correlate with QTc interval in newborns?
In newborns, heart rate variability is inversely correlated with QTc prolongation on the fourth day of life, suggesting delayed maturation or impaired functioning of the autonomic nervous system.
No takes yet. Share an insight, caveat, or question.
May indicate transient autonomic immaturity affecting neonatal QTc; hypothesis-generating for arrhythmia risk studies.
Perticone et al. (1990) studied this question.
