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 ABR阳性检出率
In order to investigate the effect of hyperlipidemia on hearing threshold, 16 elderly patients with primary hypo-hyperlipidemia who had no significant hearing loss were treated with short-sound repetition rate of 20 times / s and 40 times / s respectively To listen to the brainstem response (ABR) determination, and 12 cases of normal lipids in the elderly and 10 healthy young people as a control. Results When the short-term repetition rate increased 40 times / s, the latency and wave interval of ABR wave in hyperlipidemia group were prolonged, and there was a significant difference. The elderly with hyperlipidemia showed early hearing loss potential decline, increase the short-sound repetition rate can increase the positive detection rate of ABR
