OBJECTIVE

To analyze the features of heart rate variability in newborns with cardiorespiratory failure.

MATERIAL AND METHODS

We have analyzed 124 newborns in order to find functional explanations and relationships between different assessments of cardiac cycles in critically ill newborns using cardiointervalography.

RESULTS

Median stress index is significantly higher in newborns with cardiorespiratory failure (541.76 [166.05; 1266.05] vs. 123.08 [70.85; 352.30], p=0.000). Stress index augmentation over 1017 conventional units (Se 66.67% and Sp 89.83%) is unfavorable predictor of failed adaptation (OR 17.66; 95% CI 2.92-106.8). Wave spectrum (LF/HF) ratio in severe cardiorespiratory failure determines the dominance of sympathetic autonomic system (1.45 [0.80; 2.03] ves. 0.82 [0.64; 1.54], p=0.018). Vasopressor hemodynamic support is associated with an increase in high-frequency spectrum power.

CONCLUSION

Neonatal heart rate variability in cardiorespiratory failure is significantly reduced. Advanced activity of sympathetic autonomic system and suppression of high-frequency rhythm spectrum are associated with a critical state of the newborn.
