Background: The index of cardioelectrophysiological balance (iCEB), measured as QT interval divided by QRS duration, has recently been defined as a new risk marker for arrhythmias. Increased or decreased iCEB is associated with malignant ventricular arrhythmias. Aim: In this study, we aimed to investigate the relationship between iCEB and stroke severity in patients with acute ischemic stroke. Methods: The study comprised 105 adult patients (males, 58; females, 47; 69 ± 15 years) with acute ischemic stroke. Nine patients were excluded. Patients were divided into two groups based on the calculated National Institutes of Health Stroke Scale (NIHSS) score (Group 1, NIHSS score <16; Group 2, NIHSS score ≥16). Demographic, clinical, and laboratory data for all patients were collected. Electrocardiography (ECG) was recorded from all patients on admission to the neurology care unit. iCEB (QT/QRS) was calculated from the 12-lead electrocardiogram. Results: There were no significant differences among the demographic parameters of patients. iCEB score was significantly higher in Group 2 patients than Group 1 patients (3.97 ± 0.61 vs 3.43 ± 0.57, P = 0.0024). Conclusion: Our results suggested that iCEB is associated with stroke severity on admission in patients with acute ischemic stroke. It is known that high iCEB is associated with torsade de pointes (TdP), ventricular tachycardia.
