Markers of Ventricular Repolarization in Obstructive Sleep Apnea Abstract

Obstructive sleep apnea as defined by i) polysomnography apnea/hypopnea index or respiratory disturbance index of at least 5/hour or ii) home sleep apnea test with a respiratory event index of at least 5/hour will be included. QT, QTc intervals and QT variability will also be reviewed from electrocardiograms as the primary outcomes in subjects with obstructive sleep apnea when compared to those without obstructive sleep apnea. QT variability can be calculated by many different methods as outlined by the European Heart Rhythm Association and the European Society of Cardiology Working Group on Cardiac Cellular Electrophysiology (reference below). All methods of measuring QT variability will be included in this review. If obstructive sleep apnea is associated with any other electrocardiographic changes for instance—QT dispersion, Tp-e etc. these will also be reviewed as secondary outcomes.
