Abstract: (863 Views)
Background: In addition to heart disease, ECG also changes in non-heart disease, which due to its similarity, can lead to misdiagnosis of heart disease in patients. ECG changes in brain lesions such as ischemic and hemorrhagic strokes, brain traumas, etc. and have been studied in many articles, but the effects of brain midline shift on ECG changes have not been studied. In this study, we want to examine these changes.
Methods: This is a prospective cross-sectional descriptive study. Patients with brain tumors who were referred to Al-Zahra and Kashani hospitals in Isfahan from April 2019 to March 2021 were selected. Patients with a history of heart disease, patients receiving medications that cause ECG changes, patients with ECG changes due to non-cardiac and cerebral causes, and individuals under 15 years of age were not included in the study. Patients whose ECG changes were due to electrolyte disturbances or acute heart problems were also excluded from the study. After obtaining informed consent from patients, a CT scan or brain MRI was taken and patients were divided into two groups with and without midline shift. Then the ECG was taken and ECG changes (T wave, ST segment, QTc Interval, QRS prolongation) were compared in two groups of brain tumors with and without midline shift.
Results: 136 patients were included in the study. Of these, 69 patients were in the without midline shift group and 67 patients were in the midline shift group. In the midline shift group, 3% of patients had ST segment changes and 23.9% had T wave changes, which were 1.4% and 10.1% in the without midline shift group, respectively. The mean QTc Interval in the two groups without and with midline shift was 338.26 (4 28.438) and 388.66 (37.855), respectively, and the mean QRS in the without midline shift group was 86.09 (88.9.88) ms and in the midline shift group was 94.63 (±12.83) ms.
Conclusion: Brain midline shifts can cause QRS widening, QTc interval prolongation, and T-wave changes in patients' ECGs.
