Popis: | WOS: 000439515500013 PubMed ID: 29726590 BackgroundVentricular arrhythmias are reported to be more common in patients with obstructive sleep apnea (OSA). Preliminary evidence showed such parameters regarding ventricular repolarization as Tp-e, Tp-e/QT, and Tp-e/QTc may be related with increased cardiac arrhythmias and even sudden cardiac death. The purpose of the present study was to evaluate ventricular repolarization during immediately preapnea period, apnea period, and postapnea hyperventilation period in patients with OSA. MethodsA total of 59 patients who underwent polysomnography and were diagnosed with OSA between the years 2016-2017 in our hospital were included in our study. Of 59 patients (mean age: 52.519.66), 28 were male and 31 were female. In all patients, Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratio, together with some other parameters, were calculated. Categorical variables were expressed as proportion and continuous variables were expressed as meanstandard deviation. Electrocardiogram calculations of interest were compared through preapnea, apnea, and postapnea periods using Friedman's test. ResultsTp-e interval (85.6ms [78.3-95.6], 98ms [88.5-107.7], 91.2ms [81-98.8], respectively; P |
