Why the study?
Do specific electrocardiographic changes reflect abnormal left ventricular wall motion in patients with acute subarachnoid hemorrhage?
Population
57 patients with acute subarachnoid hemorrhage (SAH) without preexisting cardiac disease
Comparison
Serial electrocardiograms and echocardiograms vs Patients with normal left ventricular wall motion

May support ECG screening for LV dysfunction in acute SAH; hypothesis-generating and requires prospective validation before practice change.
Do specific electrocardiographic changes reflect abnormal left ventricular wall motion in patients with acute subarachnoid hemorrhage?
Symmetrical T wave inversion and severe QTc prolongation on ECG can serve as useful screening criteria for identifying myocardial dysfunction in patients with acute subarachnoid hemorrhage.
Mayer et al. (1995) studied this question.
