To clarify the heart rate (HR) slowing response during periodic breathing (PB) with apnea and its relationship to hypoxic ventilatory response (HVR), sleep studies were done in seven Japanese climbers at 5,360 m in the Kunlun mountains of China in 1986. Apnea duration (APD), arterial oxygen saturation changes (delta SaO2), and the percentage of heart rate changes (delta HR%) during PB with apnea were analyzed. The data were compared with hypoxic heart rate and ventilatory responses assessed at… CONTINUE READING
