Validation of Ambulatory Sleep Test (WP200/U) Compared In-lab Sleep Testing in Cardiac Subjects

Subjects with cardiac disorders will be tested in the sleep laboratory with a conventional full-night PSG recording along with WP 200/WP200U ambulatory sleep diagnostic device in a synchronized manner. The PSG data will be scored manually by a trained polysomnographic scorer, according to standard criteria for this clinical routine. The data obtained by the WP200/WP200U will be analyzed automatically for RDI, AHI, sleep stages, snoring (optional) and body position (optional), in addition to parameters specific to cardiac subjects. The analysis will be performed by the WP200/WP200U software (zzzPAT) and will be compared to the PSG's manual scoring which serves as a "Gold Standard".
