- May lead to sudden cardiac death
Mechanisms:
(1) Nocturnal hypoventilation → hypoxic pulmonary vasoconstriction → increased pulmonary arterial pressure → right atrial dilation
(2) Nocturnal hypoxemia → chronically elevated sympathetic tone → increased atrial conduction automaticity and increased triggering of atrial fibrillation
- OSA is also strongly associated with comorbidities that directly encourage atrial fibrillation (HTN, HFpEF)
