Introduction: ECG changes are presented in about 90% of patients with cerebral aneurysm that results subarachnoid hemorrhage (SAH). The most common site of these lesions among the cerebral arteries is anterior cerebral artery which supplies Autonomic cardiovascular centers. However it seems that the location of aneurysm influences critically on changes of ECG, which has not been studied grossly in literatures and there is no definite data to mention that. Materials and Methods: Here, a cross sectional, retrospective study was done on 500 patients presenting SAH due to cerebral aneurysm which patient´s angiography detected the location of pathology. ECG of these patients was taken two times, one on admission and other on discharge after 3rd week of admission. Results: The mean age of patients was 57.3 years old and this group included 271 male and 229 females. 388 cases had ECG changes; some of them had more than one changed factor. QRS changes were seen in 18 cases on the day of admission, QTc changes were observed in 258 cases, and changes of ST distance were observed in 126 cases. Among all of them, the location of the aneurysm was in Anterior cerebral artery in 142 cases, in communicating arteries in 84 cases, in Middle cerebral artery 64 in cases, in ICA in 36 cases and in Posterior cerebral artery in 52 cases. Conclusion: In cases which their brain angiography showed cerebral aneurysm, the frequency of ECG changes was more seen. Patients with the anterior cerebral artery aneurysms had more ECG changes. According to the obtained results, ECG of patients with SAH could be a recognized as a factor to understand better the situation of brain after SAH and be useful for managing and treating patients with SAH.
