Audiovestibular symptoms are the first and often the only clinical signs of vertebrobasilar insufficiency. The aim of our investigation was to analyze the results of caloric and electronystagmographic investigation of vascular-vestibular disorders among patients with vertebrobasilar insufficiency. We examined a total of 55 men (mean age, 51.8 +/- 8.2 years)--a primary group of 35 men with proven vascular-vestibular dysfunction and vertebrobasilar insufficiency and a control group of 20 clinically healthy men. Standard and electronystagmographic ("Tönnies" type) caloric tests were used to evaluate the human vestibular analyzer. Our data from this investigation show that in both rotatory and caloric tests, the slow-phase speed is the most important index about function of the vestibular analyzer.
视听前庭症状是椎基底动脉供血不足的首要且常常是唯一的临床体征。我们研究的目的是分析椎基底动脉供血不足患者血管性前庭疾病的冷热试验和眼震电图检查结果。我们共检查了55名男性（平均年龄51.8±8.2岁）——35名已证实存在血管性前庭功能障碍和椎基底动脉供血不足的男性为主要研究组，20名临床健康男性为对照组。采用标准和眼震电图（“托尼斯”型）冷热试验评估人体前庭分析器。我们此次研究的数据表明，在旋转试验和冷热试验中，慢相速度都是关于前庭分析器功能的最重要指标。
