TEN suppresses changes in HRV induced by experimentally induced stress.
The histograms illustrate the average HR (a), R-R interval (b), SDNN (c), LF power (d), HF power (e) and LF/HF (f) HRV responses mediated by sham and TEN treatments in response to the induction of acute stress. An asterisk indicates a significant difference with P < 0.05. All data shown are mean ± SD.
