摘　　要：为探讨血脂增高对听阈的影响 ,对 16例原发性高脂血症无明显听力减退的中老年人分别采用短声重复率 2 0次 / s与 4 0次 / s两种给声方式作了听性脑干反应 ( ABR)测定 ,并以 12例血脂正常的中老年人和 10例健康年轻人作对照。结果短声重复率增加 4 0次 / s时 ,高脂血症组的ABR波潜伏期和波间期延长 ,并有显著性差异。表明患高脂血症的中老年人听功能早期有潜在性减退 ,增加短声重复率能提高Sixteen medial and old patients with essential hyperlipidemia who are acusis were tested auditory brain stem response(ABR)with click repetition rate 20/s and 40/s,respectively.In comparison with 12 medial and old people with normallipidemia and 10 health people,the IL and IPL of ABR of the hyperlipidemia group are longer than that of other two groups.There is statistical significant difference among the 3 groups of ABR date.The result showed that the hearing function of the medial and old patients with hyperlipidemia dropped potentially in early phase.Increasing the click repetition rate can improve the detection probability of positive reaction of ABR.
