title: An uncommon electrocardiographic change in subarachnoid hemorrhage: increase in the Sokolow's Index.
abstract: In this paper we are reporting a case of electrical left ventricular hypertrophy with increased Sokolow's index following subarachnoid hemorrhage. Two-dimensional echocardiography ruled out anatomical left ventricular hypertrophy, and the Sokolow's index eventually reverted to normal. This electrocardiographic abnormality has rarely been associated with subarachnoid hemorrhage and does not appear to be related to the neurologic grade of the patient because he presented with headaches only and was conscious throughout (Hunt and Hess grade I). The possibility that such electrocardiographic changes should reflect anatomical changes in the heart should always be ruled out by proper investigations (i.e., echocardiography and coronarography), as the presence of cardiac disorders would greatly influence medical and surgical management. In terms of electrocardiography, this observation suggests that the Sokolow's index is a poor indicator of left ventricular hypertrophy, and tends to reflect a more comprehensive catecholaminergic process.
