动态心电图对睡眠呼吸暂停综合征的诊断价值及与心律失常的关系分析

目的:评估动态心电图对睡眠呼吸暂停综合征(SAS)的诊断价值并分析其与心律失常的关系。方法:选取2017年2月～2019年2月我院收治的SAS患者80例记为病变组,另取同期于我院进行体检的健康人员80例记为对照组。两组均进行动态心电图检查,并以多导睡眠监测仪检查结果为金标准,分析动态心电图诊断SAS的灵敏度、特异度以及准确度。比较两组动态心电图监测结果,心律失常以及ST-T缺血性改变发生情况。结果:动态心电图诊断SAS的灵敏度、特异度、准确度分别为92.31%、75.00%、90.00%。病变组最高心率、房性早搏次数、室性早搏次数均高于对照组,而最低心率低于对照组(均P0.05)。病变组心律失常及ST-T缺血性改变发生率均高于对照组(均P0.05)。结论:动态心电图对SAS的诊断价值较高,具有良好的灵敏度、特异度。临床工作中可通过动态心电图监测,从而及时检出心律失常及ST-T缺血性改变,进一步有效预防猝死的发生。

The Value of Dynamic Electrocardiogram in the Diagnosis of Sleep Apnea Syndrome and Its Relationship with Arrhythmia

ABSTRACT Objective: To study the diagnostic value of dynamic electrocardiogram in sleep apnea syndrome (SAS) and its relationship with arrhythmia. Methods: 80 SAS patients who were admitted to our hospital from February 2017 to February 2019 were selected as the lesion group, and 80 healthy patients who underwent physical examination in our hospital at the same time were selected as the control group. Dynamic electrocardiogram examination was performed in both groups. The sensitivity, specificity and accuracy of SAS diagnosis in dynamic electrocardiogram were analyzed with the results of polysomnography monitor as the gold standard. The results of dynamic electrocardiogram monitoring, arrhythmias and ischemic changes of ST-Twere compared between the two groups. Results: The sensitivity, specificity and accuracy of SAS were 92.31%, 75.00% and 90.00% respectively. The highest heart rate, the number of atrial premature beats and the number of ventricular premature beats in the lesion group were all higher than those in the control group, while the lowest heart rate was lower than those in the control group (all P<0.05). The incidence of arrhythmia and ST-T ischemic change in the lesion group were higher than those in the control group (both P<0.05). Conclusion: Dynamic electrocardiogram is of high diagnostic value for SAS, and it has good sensitivity and specificity. It can detect arrhythmias and ST-T ischemic changes timely through dynamic electrocardiogram monitoring in clinical work, so as to further effectively prevent the occurrence of sudden death.
