HRV parameters for healthy controls versus tinnitus patients.
| HRV parameter | Healthy controls | Tinnitus patients | P value |
|---|---|---|---|
| TP (ms2) | 7.49 ± 0.99 | 6.92 ± 1.14 | 0.020* |
| VLF (ms2) | 6.37 ± 0.92 | 6.09 ± 1.21 | 0.256 |
| LF (ms2) | 5.98 ± 1.19 | 5.54 ± 1.27 | 0.114 |
| HF (ms2) | 6.41 ± 1.19 | 5.13 ± 1.43 | 0.000** |
| LF/HF | 0.94 ± 0.11 | 2.48 ± 3.47 | 0.008** |
HRV data were log-transformed prior to statistical analysis. The values given are the mean ± SD. Statistical significance was set at a P value < 0.05, using independent sample t-test. TP: total power; VLF: very low frequency; LF: low frequency; HF: high frequency; LF/HF: ratio of absolute LF to HF power; *P < 0.05; **P < 0.01.
