目的通过动态心电图可以更好地分析交替蝉联现象发生机制、条件及心电图特征。方法回顾分析1993年1月至2014年12月间在我院住院和门诊心电图47例24h动态心电图检查符合交替蝉联现象作为观察对象,分析患者的临床特点。结果 21例(45%)为窦性心律、26例(55%)为心房颤动、扑动。房性早搏二联律诱发交替蝉联12例(26%),短阵房速、心房颤动、扑动诱发交替蝉联35例(74%)。在房颤、房扑组发作的心率、左房直径和房速组的比较无临床差异,而这两组分别和房早二联律组比较时发作心率、左房直径都有非常显著的临床差异。结论交替联蝉现象多发生于心率较快时。动态心电图能够更多发现和分析诊断交替联蝉现象,掌握这种心电现象的机制,有助于准确诊断,避免误诊。
Objectives To better analyze the mechanism of occurrence of alternation reelection, conditions and ECG characteristics by Holter monitoring. Methods A retrospective analysis of January 1997 to December 2014 in our hospital inpatient and outpatient ECG 47 cases of 24h dynamic electrocardiogram consistent with the phenomenon of alternating reelection as the observation object, analysis of the clinical features of patients. Results 21 cases (45%) were sinus rhythm, 26 cases (55%) were atrial fibrillation and flutter. Atrial premature beats induced by twins alternate reelection in 12 cases (26%), atrial tachycardia, atrial fibrillation, flutter induction alternant 35 cases (74%). In atrial fibrillation, atrial fibrillation attack heart rate, left atrial diameter and atrial tachycardia group no clinical differences, while the two groups were compared with room early diathesis group when the attack heart rate, left atrial diameter have a very significant clinical difference. Conclusion Alternate Cicada phenomenon occurs when the heart rate is faster. Holter monitoring can be more found and analyze the phenomenon of alternating cicada, grasp the mechanism of this ECG, help to accurately diagnose, to avoid misdiagnosis.
