摘　　要：目的探讨常规12导联心电图与24 h动态心电图诊断起搏器植入患者心律失常检出率的差异。方法选取接受起搏器植入手术治疗的50例患者作为本次研究对象,分别采用常规12导联心电图与24 h动态心电图两种方法对其进行检查,对比分析两组研究对象的心律失常检测结果与敏感度、特异度等情况。结果 24 h动态心电图诊断组患者心律失常检出率（50.00%）明显高于常规心电图诊断组（22.00%）,差异有统计学意义（χ^2=8.51,P〈0.05）。动态心电图检测的准确性（96.00%）、特异度（98.00%）、敏感度（96.00%）与常规心电图检测的准确性（54.00%）、特异度（58.00%）、敏感度（62.00%）相比明显较高,差异有统计学意义（χ^2=23.52、23.31、17.42,P〈0.05）。结论 24 h动态心电图诊断起搏器植入患者心律失常检出率显著高于常规12导联心电图,准确性、敏感度较好,安全可靠,值得推广应用。Objective To analyze the difference of conventional 12- lead electrocardiogram（ ECG） and 24- hour dynamic ECG in the detection of arrhythmia among the patients implanted with pacemaker. Methods Fifty patients receiving pacemaker implantation in our hospital were determined using conventional 12- lead ECG and 24- hour dynamic ECG. The arrhythmia detection rate,sensitivity,and specificity were compared in the two groups. Results The detection rate of dynamic ECG（ 50. 00%） was obviously higher than that of 12- lead ECG（ 22. 00%）,the difference was statistically significant（ χ^2= 8. 51,P〈0. 05）. The dynamic ECG showed a higher detection accuracy（ 96. 00%）,specificity（ 98. 00%）and sensitivity（ 96. 00%） than 12- lead ECG,in which the accuracy was 54. 00%,specificity was 58. 00% and sensitivity was 62. 00%,respectively,the difference was statistically significant（ χ^2= 23. 52、23. 31、17. 42,P〈0. 05）. Conclusion 24- hour dynamic ECG has a significantly higher detection rate of arrhythmia than conventional 12- lead ECG in the pacemaker- implanted patients,and shows good accuracy and sensitivity,being safe and reliable,therefore this method should be widely applied.
