Lateral medullary infarction rarely leads to central hypoventilation syndrome (CHS). CHS is a life-threatening disorder characterized by hypoventilation during sleep. We report the first case of CHS as a complication of lateral medullary infarction after endovascular treatment. A 65-year-old man presented twice with severe headache. Computed tomography revealed subarachnoid hemorrhage and cereb...

While obstructive sleep apnoea syndrome dominates discussion of the prevalence of sleep disordered breathing, nocturnal hypoventilation remains extremely prevalent in those with chronic ventilatory disorders and in the natural history of these conditions pre-dates the development of daytime ventilatory failure. In this review the clinical management of chronic hypoventilation in neuromuscular d...

933 Heart Rate Variability in Sleep Related Alveolar Hypoventilation—Palma et al INTRODUCTION Sleep related alveolar hypoventilation (SRAH) is characterized by decreased alveolar ventilation resulting in sleep related oxygen arterial desaturation in patients with normal mechanical properties of the lung. SRAH can be distinguished from central and obstructive sleep apnea (OSA) by the fact that O...
