Heat-induced MSNA rise without BP change warrants caution interpreting baroreflex data in heat; leaves open relevance to patients with cardiovascular disease.
Does whole body heating alter arterial baroreflex control of muscle sympathetic nerve activity in healthy subjects?
Whole body heating shifts the baroreflex curves for MSNA and heart rate upward to accommodate physiological changes, without altering the sensitivity of arterial baroreflex modulation.
