Suggests transient baroreflex-MSNA resetting without sensitivity loss during apnea; leaves open effects in sleep apnea syndromes.
Does voluntary apnea alter the sensitivity of carotid baroreflex control of MSNA and heart rate in humans?
The sensitivity of carotid baroreflex control of MSNA is not attenuated during apnea, suggesting a transient resetting of the baroreflex-MSNA function curve rather than a loss of sensitivity.
Swift et al. (2003) studied this question.
