Abstract
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.
