Why the study?
Do cavopulmonary connection operations reduce heart rate variability in pediatric patients compared to healthy children or those undergoing biventricular repair?
Do cavopulmonary connection operations reduce heart rate variability in pediatric patients compared to healthy children or those undergoing biventricular repair?
Cavopulmonary connections in pediatric patients are associated with significantly reduced heart rate variability and low vagal drive compared to healthy children and those undergoing biventricular repair.
No takes yet. Share an insight, caveat, or question.
May signal autonomic dysfunction in cavopulmonary connection patients; leaves open prognostic value and intervention targets.
Butera et al. (1999) studied this question.
