Objective : To evaluate autonomic nerve balance and sympathetic nerve activity in patients with inner ear dysfunction as examined by heart rate variability(HRV)
Research Methods and Procedures : One hundred and twenty three patients(between 15 to 59 years old) who visited Dept. of Oriental medical Opthalmology & Otolaryngology, Kyunghee university and had an examination of HRV test, were selected as subjects of our study. We checked items of HRV test(such as SDNN, RMSSD, LF, HF, TP, norm-LF, norm-HF, LF/HF ratio), and analyzed time and frequency domain differences between three groups classified as tinnitus, hearing loss and vertigo. And we compared HRV items(such as SDNN,RMSSD, TP and LF/HF ratio) with standard levels.
Results and Conclusion : Our results showed no significant differences between three groups in HRV items except for mean heart rate. Patients with inner ear dysfunction showed significant lower TP than 2000(ms2)(p¡´0.001) and significant higher LF/HF ratio than 1.5(p=0.003). So we suggest that patients with inner ear dysfunctions such as tinnitus, vertigo and hearing loss, have sympathetic hypertonus and inactivity of autonomic nerve regulation.
