Predictor role of heart rate variability in subarachnoid hemorrhage: A systematic review
Authors' conclusion
A correlation between absolute values or changes of the LF/HF ratio and neurologic and cardiovascular complications was found in multiple studies.
Study context
- Population
- Patients with subarachnoid hemorrhage (SAH)10 articles
- Outcome
- Early HRV changes and complications/outcome
Pooled result
As reported in the abstract
- Early changes in heart rate variability (HRV) indices (time and frequency domain) correlated with neuro-cardiogenic complications and poor neurologic outcome in SAH
- Absolute values or changes of the LF/HF ratio correlated with neurologic and CV complications in multiple studies
