Abstract
Objective To study the relationship between high/low stimulation rates ABR wave V latency differen-tial and I-V inter-peak latency differential and potential utility of wave V latency differential in diagnosing posterior cir-culation ischemia when wave I is absent. Method Seventy five subjects (male=17, female=58, mean age=48.8 ± 10.4 years, 150 ears) with normal high/low rate ABR I-V inter-peak latency differentials (≤0.28 ms) and 150 subjects (male=45, female=105, mean age=48.9 ±9.5 years, 150 ears) with abnormal I-V inter-peak latency differentials (>0.28 ms) were identified and their high (51.1/s)/low (11.1/s) rates ABR wave V latency differentials and I-V inter-peak interval differen-tials were analyzed using Pearson correlation test. Results Pearson correlation coefficient between wave V latency differ-ential and I-V inter-peak interval differential was 0.628 (P<0.001). As for comparison between wave V latency differen-tial and I-V inter-peak interval differential in diagnosis, the area under ROC (i.e. AUC) was 0.819 (P<0.001) with a corre-sponding threshold of 0.34 ms. Conclusion There is a high positive correlation and diagnostic agreement between high/low rates ABR wave V latency differential and I-V inter-peak interval differential, suggesting that the wave V latency dif-ferential can be used instead of I-V inter-peak interval differential as an alternative tool of diagnosing posterior circula-tion ischemia when wave I cannot be elicited.关键词
