... HR changes in obstructive apnoeas. According to that hypothesis, upper aiiway receptor stimulation in apnoeas could activate postinspiratory neurons; postinspiratory time could then increase and this, in turn, could contribute to HR changes. However, the authors did not perform any expiratory time m ...
