A preliminary study on the early diagnosis of sinus dysfunction in patients with obstructive sleep apnea syndrome

Summary:To observe the characteristics of sinus dysfunction (SD) in patients with obstructive sleep apnea syndrome (OSAHS) and to explore the method for early detection of SD in these patients. From January 2007 to June 2008, 119 snorers were recruited. All of them underwent polysomnography (PSG) examination and received atropine test under ultramicroelectrocardiogram (UMECG). Based on the results of atropine test, they were divided into 2 groups: the UMECG group (n = 78) including subjects diagnosed as having SD by a positive result of atropine test with UMECG, and the non-UMECG group (n = 41) including subjects with a negative result of atropine test. Comparison was made for the incidence of OSAHS between the 2 groups and the diagnostic sensitivities for SD between UMECG and PSG electrocardiogram (SD(PSG)). The association was also observed between PSG parameters and SD(PSG). The incidence of OSAHS in the non-UMECG group was significantly higher than that in the UMECG group (31% vs 55%, P < 0.05). SD(PSG) was not d
