Sleep-disordered breathing (SDB) and Atrial Fibrillation: A Case of Bidirectional Relationship and Continuous PAP Compliance Monitoring

Sleep-disordered breathing (SDB) is a contributor to atrial fibrillation (AF) and the treatment of obstructive sleep apnea can reduce the recurrence of AF following catheter ablation. On the other hand, the impact of AF therapy and conversion to sinus rhythm is not fully understood. This is a case of a middle-aged man with SDB and persistent AF who exhibited improvement in SDB events, following sinus rhythm conversion. This supports the hypothesis that a bidirectional relationship between SDB and AF exist and highlights the importance of continuous monitoring of CPAP compliance, beyond improvement of daytime sleepiness.

Consumer sleep tracking devices: What to believe?

Consumer sleep technologies (CSTs) such as fitness trackers and smartphone apps have become increasingly popular. Most of these devices appear to utilize data generated from in-built accelerometers to determine sleep parameters but the exact mechanisms and algorithms are proprietary. These devices claim to measure the sleep duration of their users and in some cases purport to measure sleep quality, sleep stages including REM sleep. The growing literature comparing these devices against polysomnography/actigraphy shows that they tend to underestimate sleep disruptions and overestimate total sleep times and sleep efficiency in normal subjects. This American Academy of Sleep Medicine position statement details the advantages and disadvantages of CSTs and provides guidance when approaching patient-generated health data from CSTs in a clinical setting.
