BACKGROUND In patients with obstructive sleep apnea syndrome (OSAS), there are cyclic fluctuations in heart rate (HR), that is, bradycardia during apnea followed by abrupt tachycardia on resumption of ventilation. Although a previous study suggested that the degree of bradycardia observed during central apnea at high altitude was determined by individual hypoxic chemosensitivity of the carotid body, it is not known whether this is true for subjects with obstructive sleep apnea syndrome… CONTINUE READING
