12导动态心电图在病窦综合征诊断中的应用价值

目的：探讨12导动态心电图在病窦综合征诊断中的临床意义。方法选取经临床确诊的40例病窦综合征患者作为观察组，另选取同期40例健康者作为对照组，比较两组人群的动态心电图结果。结果观察组最快心率，最慢心率、24 h平均心率和24 h总心率均低于对照组，差异有统计学意义(P<0．05)；观察组窦性心动过缓、窦性停搏、窦房阻滞、交界性逸搏心律及慢快综合征等心律失常检出率均高于对照组，差异有统计学意义(P<0．05)。结论12导动态心电图可全面观察患者心律和心率变化，显著提高心律失常检出率，是早期诊断病窦综合征一项必不可少的检测方法。

The application value of 12-lead dynamic electrocardiogram in diagnosis of sick sinus syndrome

Objective To investigate the clinical significance of 12-lead dynamic electrocardiogram in the diagnosis of sick sinus syndrome( SSS) . Methods Forty cases with SSS were selected as the observation group and 40 healthy people as the control group. The 24 hour dynamic electrocardiogram data were compared, including 24 hour total heart rate, average heart rate, maximum heart rate, lowest heart rate and the detection rate of arrhythmia. Results 24 hour total heart rate, average heart rate, maximum heart rate, lowest heart rate of the observation group were lower than those of the control group, and the difference was statistically significant(P<0. 05). The detection rate of arrhythmia, such as sinus bradycardia, sinus arrest, sinoatrial block, junctional escape rhythm, bradycardia-tachycardia syndrome etc. in observation group was obviously higher than that of control group, and the difference was statistically significant(P<0. 05). Conclusion 12-lead dynamic electrocardiogram can fully observe the change of rhythm and heart rate of patients and significantly improve the detectable rate of arrhythmia. 12-lead dynamic electrocardiogram is an indispensable testing method for early diagnosis of SSS.
