Medical teams may soon rely on a novel electrocardiographic (ECG) parameter—the frontal f-QRST angle—for assessing the severity of aneurysmal subarachnoid hemorrhage (SAH). Researchers at Haseki Training and Research Hospital have concluded a study examining the predictive capabilities of this parameter with the Hunt-Hess and modified Fisher scales as comparative tools.
The results are relevant for clinical, quality, and regulatory teams involved in developing diagnostic criteria and medical devices that aid stroke and neurovascular care.
What is the f-QRST angle?
The f-QRST angle is an electrocardiographic measurement related to cardiac electrical activity. It assesses the spatial orientation of electrical vectors in the heart during ventricular depolarization and repolarization phases. Previous studies have indicated its potential in predicting certain cardiac conditions.
This study aimed to explore its utility in neurovascular disorders, particularly its correlation with the severity of SAH as graded by standard scales.
Why does this matter?
A precise severity assessment is critical for patients suffering from aneurysmal SAH. Current methods, such as the Hunt-Hess scale and modified Fisher scale, rely on clinical observation and imaging, which can sometimes be subjective or time-consuming.
The integration of ECG-derived parameters like the f-QRST angle may offer a faster, objective alternative, providing healthcare teams with additional tools for maximizing care efficiency and outcomes.
Study details
Haseki Training and Research Hospital conducted a completed clinical trial evaluating the role of the f-QRST angle in patients with confirmed aneurysmal subarachnoid hemorrhage. The study applied standard grading systems, the Hunt-Hess scale and modified Fisher scale, to establish benchmarks for severity.
Though detailed outcomes remain pending publication, participants and researchers emphasized the need for further exploration into the relationship between cardiac electrical activity and neurovascular events.

FAQ
-
What is Subarachnoid Hemorrhage?
Subarachnoid hemorrhage is a severe type of stroke involving bleeding into the space surrounding the brain, often caused by aneurysm rupture.
-
How is the f-QRST angle measured?
It is calculated using a standard 12-lead ECG by examining the frontal electrical vectors during ventricular activity.
-
Could this be incorporated into medical devices?
The findings suggest potential for future development of SAH-specific diagnostic tools incorporating ECG technology.
Conclusion
The study highlights the importance of exploring cardiac parameters as markers for neurovascular diseases. Healthcare professionals, regulatory teams, and manufacturers should monitor emerging findings from this field to support next-generation diagnostic technologies.
