Clinical Analysis of Postoperative Patients with Electrocardiographic Abnormalities Associated with Aneurysm

ABSTRACT

Preoperative assessment of electrocardiographical(EKG) abnormalities in the patients with subarachnoid hemorrhage(SAH) is importment. Authors analyzed 58 SAH patients who had EKG abnormalities of neurogenic origin. EKG abnormalities consisted of T wave abnormality, arrhythmia, ST segment change, QT prolongation and U wave. Five patients were dead in this study because of brain swelling(3 cases) and cerebral spasm(2 cases). EKG abnormalities were normalized 13 days after aneurysmal SAH. Radioactive nuclear(99mTc-pyrophosphate) scan of myocardial revealed normal findings in the patients with EKG abnormalities of neurogenic origin. It is concluded that life-saving surgical intervention need not be delayed in the patients with EKG abnormalities of neurogenic origin. On the other hand, patients who had cardiac origin EKG abnormalities need a careful and detailed preanesthetic cardiac evaluation.
