Objective To investigate the aplication value of dynamic electrocardiogram in diagnosis of sleep apnea syndrome( SAS) in the elderly in order to provide reliable basis for diagnose and treatment of the disease. Methods Eighty-four elderly patients with suspected SAS who were treated in our hospital from October 2014 to May 2016 were enrolled in the study. All the patients were examined by polysomnography,then according to the examination results,these patients were divided into SAS group( n = 48) and non-SAS group( n = 36). The patients in both groups were examined by dynamic electrocardiogram monitoring and arterial blood oxygen items detection,respectively. The examination results of dynamic electrocardiogram and arterial blood oxygen index detection were anlyzed and compared between the two groups,moreover,the results were compared with those by polysomnography. In addition the sensitivity and specificity of dynamic electrocardiogram in diagnosis of SAS were evaluated. Results The sensitivity and specificity of dynamic electrocardiogram in diagnosis of SAS were 93. 75%,91. 67%,respectively. The levels of MSa O2 and LSa O2 in SAS group were significantly lower than those in non SAS group( P 0. 05),however,the levels of SIT90 and ODI in SAS group were significantly higher than those in non SAS group( P 0. 05). In SAS group,there were 18 cases of abnormal ECG,which accounted for 37. 5%,however,in non SAS group,there were 3 cases of abnormal ECG,which accounted for 8. 33%,there were significant differences between two groups( P 0. 01). In comparison of nighttime dynamic electrocardiogram,the highest heart rate in SAS group was obviously higher than that in non SAS group( P 0. 05),however,the lowest heart rate was significantly lower than that in non SAS group( P 0. 05),moreover the mean heart rate in SAS group was significantly higher than that in non SAS group( P 0. 05).Conclusion The application of dynamic electrocardiogram in diagnosis of SAS in the elderly is a simple,practical and reliable means,which can screen SAS more exactly,thus,which play an important role in prevention of cardiovascular and cerebrovascular diseases in the elderly.
