摘 要:Background:Obstructive sleep apnea syndrome (OSAS) is a disease with increasing prevalence,which is mainly characterized by increased cardiopulmonary mortality and *** is well-known that OSAS patients have increased prevalence of cardiovascular diseases including coronary heart disease,heart failure,and *** aim of this study was to evaluate the presence of prolonged and fragmented QRS complexes,which have previously been associated with cardiovascular mortality,in OSAS ***:Our study included 51 patients (mean age 41.6 ± 10.1 years) who were recently diagnosed with OSAS (apnea-hypopnea index [AHI] ≥5 events/h) and never received *** control group consisted of 34 volunteers (mean age 43.1 ± 11.6 years) in whom OSAS was excluded (AHI 〈5 events/h).The longest QRS complexes was measured in the 12-lead electrocardiogram (ECG) and the presence of fragmentation in QRS complexes was ***:Fragmented QRS frequency was significantly higher in patients with OSAS (n =31 [61%] vs.n =12 [35%],P =0.021).QRS and QTc durations were also significantly longer in OSAS patients than controls (99.8 ± 13.9 ms vs.84.7 ± 14.3 ms,P 〈 0.001;411.4 ± 26.9 ms vs.390.1 ± 32.2 ms,P =0.001,respectively).Analysis of the patient and controls groups combined revealed a weak-moderate correlation between AHI and QRS duration (r =0.292,P =0.070).OSAS group had no correlation between AHI and QRS duration (r =-0.231,P =0.203).Conclusions:In our study fragmented QRS frequency and QRS duration were found to increase in OSAS *** parameters are related with increased cardiovascular *** the prognostic importance of ECG parameters,it may be reasonable to recommend more detailed evaluation of OSAS patients with fragmented or prolonged QRS complexes with respect to presence of cardiovascular diseases.
