Benign paroxysmal vertigo (BPV) is a disorder of the vestibular labyrinth. The clinical features can be explained by an abnormality in the posterior semicircular canal. Under the influence of gravity, a density differential between the endolymph and the cupula will cause displacement of the cupula when changes in head position occur. The presence or absence of fatiguability is a useful test as it helps define etiology, prognosis, and therapy. At the risk of adding yet another classification of nystagmus to the literature, we submit that division of BPV into two types (fatiguable and nonfatiguable) will simplify and rationalize the management of this common complaint.
良性阵发性眩晕（BPV）是一种前庭迷路疾病。其临床特征可通过后半规管异常来解释。在重力影响下，当头位发生变化时，内淋巴与壶腹嵴之间的密度差异会导致壶腹嵴移位。是否存在疲劳性是一项有用的检查，因为它有助于明确病因、预后和治疗方法。冒着在文献中增加另一种眼球震颤分类的风险，我们认为将BPV分为两种类型（可疲劳型和不可疲劳型）将简化并使这种常见病症的管理更加合理。
