HRV parameters | Resting | Active-taVNS | Sham-taVNS | F | p |
---|---|---|---|---|---|
RMSSD | 3.38 (0.49) | 3.57 (0.56)ab | 3.38 (0.51) | 5.65 | 0.006 |
SDNN | 3.66 (0.36) | 3.80 (0.35)ab | 3.67 (0.28) | 5.25 | 0.008 |
LF | 6.71 (0.64)ac | 7.00 (0.55)a | 6.99 (0.53)c | 4.47 | 0.02 |
HF | 5.94 (1.01)a | 6.28 (0.93)ab | 5.83 (0.89)b | 5.52 | 0.007 |
Notes:
Resting vs. taVNS: p < 0.05.
Sham vs. taVNS: p < 0.05.
Sham vs. Resting: p < 0.05.
taVNS, transcutaneous auricular vagus nerve stimulation; SDNN, standard deviation of the RR intervals; RMSSD, root mean squared differences of successive RR intervals; LF, low frequency; HF, high frequencies.
