长程动态心电图对心律失常的检出率分析

Detection rate of arrhythmia by long-term Holter

目的:研究长程动态心电图对心律失常的检出率,以避免不必要的漏诊。方法:回顾性分析2017年8月1日至2019年11月30日在南昌大学第二附属医院先后行24 h动态心电图、长程动态心电图检查患者的临床资料。结果:205例中,长程动态心电图对总心律失常的检出率(91.20%)高于24 h动态心电图对总心律失常的检出率(74.10%),差异有统计学意义(P<0.05)。长程动态心电图对快速房性心律失常、阵发性房颤、频发室早等的检出率均高于24 h动态心电图(P<0.05或P<0.01)。结论:长程动态心电图对偶发、短暂发作心律失常的检出率比24 h动态心电图态更具优势,可减少漏诊。

Objective:To study the detection rate of arrhythmia by long-term Holter,and to avoid unnecessary missed diagnosis.Methods:The clinical data of patients receiving 24 h Holter and long-term Holter from August 1,2017 to November 30,2019 in Second Affiliated Hospital of Nanchang University were retrospectively analyzed.Results:Among 205 people,the detection rate of total arrhythmia by long-term Holter was significantly higher than that by 24 h Holter(91.20%vs 74.10%,P<0.05).The detection rates of atrial tachyarrhythmias,paroxysmal atrial fibrillation,frequent ventricular premature beat,etc.by long-term Holter were higher than those by 24 h Holter(P<0.05 or P<0.01).Conclusion:Long-term Holter has more advantages than 24 h Holter in the detection rate of sporadic and transient arrhythmia,which can reduce missed diagnosis.
