Abstract		Background. Subarachnoid hemorrhage may be associated with cardiac abnormalities, including arrhythmia and other electrocardiographic changes. The mechanism still remains obscure. The aim of our study was to assess with spectral analysis of heart rate variability, the role of the autonomic nervous system in provoking such abnormalities. Methods. In 21 subarachnoid hemorrhage patients (23 to 60 years old), one-channel computer-based electrocardiogram was daily recorded for spectral analysis of heart rate variability within the first week and after a period of no less than 60 days after hemorrhage. The results of spectral analysis obtained during the first week after hemorrhage were compared with those obtained from age and gender matched group of healthy volunteers, as well as with those recorded in patients at least 60 days later. Results. Spectral analysis of heart rate variability did not reveal sympathetic byperactivity, but contrary to expectations, a statistically significant vagal hyperactivity on days 4 to 6 after the incident, when compared to results obtained both after more than 60 days later (p less th. 0.03) and in the control gorup (p less th. 0.04).
