From: Myocardial function at the early phase of traumatic brain injury: a prospective controlled study
Left ventricle ejection fraction (LVEF) in patients with traumatic brain injury (TBI, n = 20 patients) and in control patients (n = 20 patients) obtained by conventional cardiac ultrasonography using the Simpson’s method. Echocardiography was performed within the first post-traumatic 24 h in the TBI group and under general anesthesia/mechanical ventilation in the control group. Values are median and extreme
