A retrospective analysis of electronystagmography (ENG) subtests performed on 93 acutely dizzy patients in the emergency room (ER) shows that "pendular tracking" has high sensitivity and specificity for determining central pathology. Small combinations of subtests altered sensitivity or specificity only slightly over pendular alone. Detection of spontaneous nystagmus was also helpful in ruling out "other" diagnoses such as hyperventilation syndrome, psychogenesis, or malingering. Popularity of the shortened ENG in the ER was evidenced by the high rate of charting of results and the frequency with which the test was requested after the study terminated. ENG also identified four cases of previously unsuspected central nervous system (CNS) lesion.
对93例急诊室急性眩晕患者进行的眼震电图（ENG）子测试的回顾性分析表明，“摆动跟踪”对确定中枢性病变具有高敏感性和特异性。子测试的小组合仅比单独的摆动测试略微改变了敏感性或特异性。检测自发性眼震对排除“其他”诊断（如过度通气综合征、精神源性或诈病）也有帮助。缩短版ENG在急诊室的高使用率体现在结果记录率高以及研究结束后该测试被要求的频率上。ENG还发现了4例先前未被怀疑的中枢神经系统（CNS）病变。
