Insights
Subarachnoid hemorrhage (SAH) frequently causes electrocardiographic (ECG) changes, including QT interval lengthening and T wave abnormalities. These ECG alterations can impact the overall clinical course of patients with SAH.
Area of Science:
- Neurology
- Cardiology
- Medical Diagnostics
Background:
- Electrocardiographic (ECG) alterations are commonly observed in patients with subarachnoid hemorrhage (SAH).
- Frequent anomalies include QT interval lengthening, T wave abnormalities, ST segment elevation/depression, and U waves.
Purpose of the Study:
- To report ECG changes in 70 cases of SAH secondary to intracranial aneurysm rupture.
- To review the literature on the pathogenesis and clinical impact of ECG changes in SAH.
Main Methods:
- Retrospective analysis of ECG findings in 70 SAH patients.
- Literature review focusing on ECG changes and their clinical implications.
Main Results:
- Detailed ECG anomalies observed in the studied SAH cohort.
- Compilation of reported ECG changes and their potential mechanisms.
Conclusions:
- ECG alterations are a significant finding in SAH patients.
- Understanding these changes is crucial for managing the clinical course of SAH.
Abstract:
Electrocardiographic (ECG) alterations in the course of sub-arachnoid hemorrhage (SAH) have frequently been reported. The most frequent anomalies reported were lengthening of the QT interval, very negative or positive deep T waves, elevation or depression of the ST segment and the presence of U waves. We report 70 cases of SAH secondary to rupture of intracranial aneurysm (part of a larger group of 150) with ECG changes. We review the literature with particular regard to discussion of the possible pathogenesis of ECG changes and to the way they may affect the general clinical course.
