Background: Positive pressure therapy (CPAP) in patients with cardiac arrhythmias and obstructive sleep apnea (OSAS) may have favorable effects by correcting intermittent hypoxemia and sympathetic activation.
Objective: To assess the effect of CPAP added to pharmacological treatment in the rate control and prevention of arrhythmias recurrence in patients with OSA.
Materials And Methods: Prospective, interventional study study which included patients diagnosed with OSAS (cardiorespiratorypolygraphy, AHI>5/hour), and arrhythmias (ECG, Holter ECG), divided in two groups: group A (pharmacological therapy only) and group B (pharmacological therapy and CPAP).
