The article presents information about nocturnal atrial Fibrillation in a patient with obstructive sleep apnoea A 75 year old woman was suspected to be suffering from sleep apnoea. Her medical history mentioned arterial hypertension and paroxysmal atrial fibrillation (AF). Polysomnography revealed obstructive sleep apnoea (OSA). During one phase of OSA the heart rate, determined by signals derived from pulse oximetry, showed a sharp rise in frequency. OSA has been reported to be associated with an increased risk of recurrence of AF after primarily successful electrical cardioversion,1 and sleep disordered breathing has been found to be very common in patients with AF.
