[ABR feature of medial and old patients with hyperlipidemia].
Sixteen medial and old patients with essential hyperlipidemia who 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.
