良性阵发性位置性眩晕在发病期间的诱发性眼震,最早由Barany描述,向下凝视主要为旋转性眼震,而取相反方向注视时出现以斜形(朝额部)方向为主的眼震。几年来作者整理了被确诊为阵发性位置性眩晕的患者1000例以上,绝大多数病例的眼震呈旋转-直线型,如头部置于侧位时,眼向下注视,观察到的眼震为旋转型,快相朝下;若向对侧凝视。查见快相向上的直线-斜形眼震,持续时间短于25～30秒,然而,在全部患者中,估计有1％病人其眼震类型、发作持续时间或二者均与上述记述不同,因此作者特将这部份
Induced nystagmus during the onset of benign paroxysmal positional vertigo was first described by Barany, with downward goniosis primarily of rotational nystagmus and obliquely (gait) in the opposite direction Nystagmus. Over the past few years, the authors sorted out more than 1,000 patients diagnosed with paroxysmal positional vertigo, the nystagmus in most cases being rotational-linear, with the eyes gazing downward as the head is placed in the lateral position and the observed Nystagmus is rotational type, fast phase down; if the opposite side of the gaze. A fast, straight line oblique oblique nystagmus was found with a duration of less than 25-30 seconds, however, in all patients, an estimated 1% of patients had a different nystagmus type, duration of attack, or both , So the author especially this part
