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 in-laboratory polysomnography.
We aimed to (1) determine the sleep architecture in arrhythmia patients; (2) detect differences 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.
The mean age was 64±13 years (70% males).
OSA (AHI ≥ 5/h) was detected in 85% of patients.
In the total sample, the sleep efficiency was reduced, and sleep onset latency was longer compared to a reference population of the same age.
In patients with OSA, the sleep efficiency and the percentage of slow wave sleep were reduced; however, the arousal and periodic limb movement indices were increased compared to patients without OSA.
The 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 (p=0.02).
There were no other significant differences in the sleep architecture, respiratory indices, and other sleep parameters between the first and the second night of the ambulatory sleep recording.
Conclusions.
There is no significant difference in the respiratory parameters obtained during two consecutive nights of ambulatory sleep testing.
Ambulatory studies incorporating EEG may provide a reliable, convenient, and economically efficient method for sleep assessment and there appears to be no significant night-to-night variability.
