MSNA burst frequency (bursts/minute, top) and incidence (bursts/100 heart beats, bottom) absolute data during the pre-ingestion, post-ingestion and hAIHT time points. *, different from pre-ingestion; †, different from post-ingestion; ‡; different from N-AC corresponding timepoint. N-AC substantially reduced hAIHT sympathoexcitation. MSNA bursts/min: time point, P<0.001; treatment, P=0.047; time point x treatment, P=0.15. MSNA bursts/100 heart beats: time point, P <0.001; treatment, P=0.02; time point x treatment, P=0.07.
