Introduction: The J wave or Osborn wave is the most characteristic E.C.G. manifestation of hypothermia. There have been very few reports of the presence of Osborn waves in patients with SAH. The mechanism of Osborn waves in non-hypothermic conditions like SAH is not yet known. Gussak et al have hypothesized that abnormality within the autonomic nervous system probably responsible for these changes. Aims and objectives: to study of incidence of Osborn waves in patients with subarachnoid hemorrhage. Material and Method: All he patients with cebrovascular accidents were included in the study. The study population consisted of 14 cases of subarachnoid hemorrhage, 22 cases of cerebral infraction and 22 cases of cerebral hemorrhage and. A 12 lead ECG was taken on the day of admission in all patients of subarachnoid hemorrhage and the finding of Osborn waves were noted. Results: Total 14 cases of subarachnoid hemorrhage and out of them 93% cases showed abnormal ECG pattern. 50% of patients with subarachnoid hemorrhage showed Osborn waves in the E.C.G. There was only one cases of primary sub arachnoids hemorrhage and it showed Osborn waves in the E.C.G. It was seen that 46% of patients with S.A.H. secondary to intracerebral hemorrhage had Osborn wave in the E.C.G. Conclusion: Osborn waves were seen in 50% of patients with subarachnoid hemorrhage. The presence of Osborn waves can be used as a diagnostic pointer to subarachnoid hemorrhage.
