The Effect of Early Surgery on Electrocardiographic Changes in Patients with Subarachnoid Hemorrhage

To investigate the effects of early surgery on electrocardiographic (ECG) parameters in patients with aneurysmal subarachnoid hemorrhage (SAH). We compared the parameters from ECGs performed preoperatively and on the 2nd and 8th days after surgery with those of normal individuals.

Eighteen patients with aneurysmal SAH (as the study group) and 22 healthy subjects (as the control group) were enrolled in this study. The demographics and ECG data of the participants were collected, and the groups were compared. The analyzed data included HR, QRS duration, Pmax, Pmin, P wave dispersion (PWD), QT, QTc, Tp-e, JT, JTc, Tp-e/QT, Tp-e/QTc, Tp-e/JT, and Tp-e/JTc. The preoperative and postoperative 2nd and 8th day values were compared.

The preoperative QT, QTc, JT, JTc, Pmax, and Pmin values of patients with aneurysmal subarachnoid hemorrhage were significantly higher than those of healthy subjects. There were no significant differences in the 2nd and 8th day ECG parameters of the groups.

Early and successful surgery for SAH can alleviate ECG changes. This may decrease the requirement for cardiac interventions in these patients.
