Abstract
Background: We aimed to prospectively investigate the changes in the electrocardiography (ECG) and the echocardiography of the patients with subarachnoid hemorrhage (SAH) before and after treatment, and to evaluate the overall role of the findings on early patients’ outcome. Methods: All consecutive patients with SAH were evaluated with on-admission ECG and echocardiography. For those with an abnormal result, a second evaluation was performed after the therapeutic interventions. All of the participants were followed until discharged or possibly expired in the hospital. Proper statistical methods were used to compare the changes between the two groups of the patients: the “expired” group, and the “discharged” group. Results: Of the total of 60 subjects, 25 (41.6%) and three (5%) had an abnormal ECG and echocardiography that were dropped to four (6.7%) and one (1.7%) after treatment, respectively. The most frequent ECG finding was T-wave inversion. Six subjects (10%) were expired in the hospital. Abnormal primary ECG was found in five out of the six dead subjects (83.3%) and 20 out of the 54 discharged ones (37%) (P = 0.029). None of the three patients with abnormal primary echocardiograms were expired during the hospitalization. Conclusion: Most SAH-induced changes in the ECG and the echocardiography are transient and reversible. Abnormal ECG is a good predictor of inpatient mortality, but abnormal echocardiography is not.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
