Abstract

Twenty-five hyperlipidemic, neurologically and audiologically asymptomatic patients were compared to 20 normolipemic control subjects regarding different interpeak latency differences (IPLD) of auditory brain stem evoked potentials (ABEP). ABEP were recorded in response to click stimuli presented at a rate of 10/sec and 55/sec. The net effect of increasing stimulus rate (ISR) on IPLD of ABEP was significantly greater in the hyperlipidemic patients for IPLD (V-I) and IPLD (III-I). ISR of ABEP indicates a trend of subclinical impairments of brain stem function in hyperlipidemic patients, probably due to ischemia accelerated by their condition.

摘要

将25名血脂异常、神经学和听力学无症状的患者与20名血脂正常的对照受试者就听性脑干诱发电位（ABEP）的不同峰间潜伏期差异（IPLD）进行比较。记录ABEP对以10次/秒和55次/秒速率呈现的点击刺激的反应。对于IPLD（V-I）和IPLD（III-I），刺激速率增加（ISR）对血脂异常患者ABEP的IPLD的净效应显著更大。ABEP的ISR表明血脂异常患者脑干功能存在亚临床损伤的趋势，可能是由于其病情加速了缺血。
