Neighbor Finds Man on Knees, Vomiting

ANSWER

The correct interpretation of this ECG includes atrial fibrillation and ST- and T-wave changes consistent with a central nervous system hemorrhage, as well as a markedly prolonged QT interval.

The most common ECG alterations seen in cases of acute subarachnoid hemorrhage include repolarization abnormalities due to imbalance of autonomic cardiovascular control. While ST depression is more common in patients with poor outcomes, it is not predictive.
