[摘要] 目的 研究动态心电图在诊断病态窦房结综合征中的应用价值，提高临床诊断准确率，使患者得以及时治疗。方法 取2013年3月～2015年3月在我院就诊的70例病态窦房结综合征患者作为实验组，选取70例健康志愿者作为对照组，24h检查其动态心电图，比较两组的最高心率、最低心率、24h平均心率和24h总心搏数，比较两组心房颤动、窦性停搏、窦性心动过缓、窦房阻滞等心律失常的发生率。 结果 实验组最高心率、最低心率，24h平均心率、24h总心搏数均比对照组低，差异具有统计学意义（P<0.05）；实验组心房颤动、窦性停搏、窦性心动过缓、窦房阻滞等心律失常的发生率比对照组高，差异具有统计学意义（P<0.05）。70 例病态窦房结综合征患者中Ⅰ、Ⅱ、Ⅲ、Ⅳ型分别为24例、12例、6例、28例。 结论 动态心电图诊断病态窦房结综合征简单方便、准确性高、无创伤，值得在临床诊断病态窦房结综合征中推广应用。

[Abstract] Objective To study the application of dynamic electrocardiography in the diagnosis of sick sinus syndrome， to improve the accuracy of diagnosis， so that patients can be treated in time. Methods From March 2013 to March 2015 in our hospital，70 cases with sick sinus syndrome were picked as the observation group，70 healthy volunteers were picked as the control group， they were given 24h dynamic electrocardiography check， the maximum heart rate， minimum heart rate， 24 h and 24 h total average heart rate heart rate were compared， arrhythmias incidences such as atrial fibrillation， sinus arrest， sinus bradycardia， sinoatrial block were also compared. Results Maximum and minimum heart rate， the average heart rate and the total heart beats during 24 hours of the observation group were lower than the control group， the differences were statistically significant（P<0.05）.Arrhythmias incidence such as atrial fibrillation， sinus arrest， sinus bradycardia， sinoatrial block of the observation group were higher than the control group， the differences were statistically significant（P<0.05）. 70 cases of patients with sick sinus syndrome Ⅰ， Ⅱ， Ⅲ， Ⅳ type were 24 cases， 12 cases， 6 cases， 28 cases. Conclusion Dynamic electrocardiography is simple， convenient， highly accurate， non-invasive， and it should be widely applied in the diagnosis of sick sinus syndrome.

病态窦房结综合征是由窦房结的器质性病变导致窦房结形成或传出冲动障碍而引起的心律失常综合征[1]，会导致心、脑等器官供血不足，造成严重后果，早期诊断病态窦房结综合征对确保患者健康具有十分重要的意义[2]。常规心电图不易发觉夜间窦性心动过缓且影响人的正常活动[3]。动态心电图在诊断中具有随身、连续、实时、长时记录、可靠、无创等优点，能够有效捕捉易出现在夜间的间歇性发生的窦性心动过缓[4]，受到临床医务工作者极大的关注与重视。为分析动态心电图在诊断病态窦房结综合征中的应用价值，本研究选取了2013年3月～2015年3月在我院就诊的70例病态窦房结综合征患者和70例健康志愿者作为研究对象，现将结果报道如下。
