Heat stress MSNA spectral shifts should not change clinical practice; leaves open links to blood pressure variability in patients.
Does whole body heating alter the spectral characteristics of muscle sympathetic nerve activity and systolic blood pressure variability in healthy subjects?
Whole body heating alters the spectral characteristics of muscle sympathetic nerve activity by increasing the high-frequency component, but these changes do not parallel the heat stress-induced reductions in systolic blood pressure variability.
