A transition of alpha to theta pattern coma is documented in a case of fatal cerebral anoxia after a cardiac arrest. The patient was a 35-year-old woman who suffered a cardiac arrest due to myocardial ischaemia and ventricular tachycardia. Altogether 6 EEGs showing progressive deterioration were performed during the 11 days of survival. There was histopathological evidence of extensive ischaemic damage involving cerebral and cerebellar cortex, basal ganglia and brainstem structures. Although closed chest cardiopulmonary resuscitation was begun with minimal delay after cardiac arrest, the outcome may reflect the increasingly documented failure of this type of resuscitation to provide adequate organ perfusion during cardiac arrest.
一例心脏骤停后发生致命性脑缺氧的病例记录了从α波昏迷模式向θ波昏迷模式的转变。患者为一名35岁女性，因心肌缺血和室性心动过速发生心脏骤停。在存活的11天里共进行了6次脑电图检查，显示病情逐渐恶化。组织病理学证据表明，广泛的缺血性损伤累及大脑和小脑皮质、基底神经节和脑干结构。尽管在心脏骤停后立即以最短的延迟开始了胸外心脏复苏，但结果可能反映出这种复苏方式在心脏骤停期间未能提供足够的器官灌注这一情况越来越常见。
