Key result
Atrial fibrillation was an independent predictor of poor sleep quality (OR 3.36; 95% CI 2.00-5.55), and maintenance of sinus rhythm after cardioversion significantly improved sleep quality scores.

AF-associated poor sleep may improve with sinus rhythm maintenance after cardioversion; leaves open need for RCTs before practice change.

Does direct current cardioversion improve sleep quality in patients with persistent atrial fibrillation?
Effect estimate: OR 3.36 (95% CI 2.00-5.55)
Absolute Event Rate: 76% vs 45%
p-value: p=<0.001
Patients with atrial fibrillation have poorer sleep quality than controls, which significantly improves following successful restoration and maintenance of sinus rhythm via cardioversion.
Kayrak et al. (2013) conducted an observational in Atrial fibrillation (n=303). Direct current cardioversion vs. Age-matched controls (stage 1) / AF recurrence (stage 2) was evaluated on Poor sleep quality (global PSQI score > 5) (OR 3.36, 95% CI 2.00-5.55, p=<0.001). Atrial fibrillation was an independent predictor of poor sleep quality (OR 3.36; 95% CI 2.00-5.55), and maintenance of sinus rhythm after cardioversion significantly improved sleep quality scores.
