Introduction. Obstructive sleep apnea (OSA) is common and usually underdetected in patients with cardiac arrhythmia. Ambulatory sleep testing may provide an alternative method for detection of OSA under realistic conditions compared to inlaboratory polysomnography. We aimed to (1) determine the sleep architecture in arrhythmia patients; (2) detect diferences in sleep parameters between patients with and without OSA; and (3) compare the results of two consecutive nights of unattended ambulatory sleep testing. Methods. Consecutive patients with unknown OSA status were recruited from arrhythmia clinics. Patients underwent two consecutive nights of self-applied in-home sleep testing replete with electroencephalogram (EEG) recording. Results. One hundred patients were recruited. Te mean age was 64 ± 13 years (70% males). OSA (AHI ≥ 5/h) was detected in 85% of patients. In the total sample, the sleep efciency was reduced, and sleep onset latency was longer compared to a reference population of the same age. In patients with OSA, the sleep efciency and the percentage of slow wave sleep were reduced; however, the arousal and periodic limb movement indices were increased compared to patients without OSA. Te two nights of the ambulatory sleep testing showed consistent results with an excellent test-retest reliability for the AHI (ICC = 0.813). REM latency was shorter during the second night of sleep recording (� = 0.02). Tere were no other signifcant diferences in the sleep architecture, respiratory indices, and other sleep parameters between the frst and the second night of the ambulatory sleep recording. Conclusions.Tere is no signifcant diference in the respiratory parameters obtained during two consecutive nights of ambulatory sleep testing. Ambulatory studies incorporating EEG may provide a reliable, convenient, and economically efcient method for sleep assessment and there appears to be no signifcant night-to-night variability.

5. Conclusion

In conclusion, a technically adequate unattended ambulatory sleep monitoring with full sleep assessment may provide an afordable and practical solution that may aid in early detection and treatment of OSA and several sleep disorders. Tis opens the prospect of sleep evaluation as a front-line medical service rather than a tertiary clinical service and allows family physicians, for example, to become involved in performing this important health metric.
