| Popis: | We report a patient with transient advanced atrioventricular (AV) block induced by obstructive sleep apnea (OSA). This 54-year-old man was diagnosed as having severe OSA and AV block with ventricular asystole for more than 6 s during overnight polysomnography, which occurred just from the onset of OSA before oxygen desaturation had occurred. An electrophysiological study revealed normal AV conduction system function and normal His-Purkinje system function. The resolution of OSA with continuous positive airway pressure therapy improved the advanced AV block. Therefore, the bradyarrhythmia was determined to be an OSA-induced AV block that occurred before oxygen desaturation. |
