目的探讨2:1房室阻滞伴干扰性房室脱节的心电图诊断。方法回顾分析12例2:1房室阻滞伴干扰性房室脱节患者的心电图。结果酷似三度房室阻滞的12例心电图,根据三度房室阻滞诊断标准“房室分离且RR间期>2倍PP间期,心室率<50bpm,心房率<135bpm”均可明确诊断为2:1房室阻滞合并干扰性房室脱节,交界性逸搏;伴发室性早搏8例,房室早搏2例,ST-T改变4例。结论伴有逸搏干扰的房室阻滞常使心电图复杂化,造成阻滞程度加重的伪象,易造成误诊,认真分析动态心电图有助于鉴别诊断。
Objective To investigate the ECG diagnosis of 2: 1 atrioventricular block with disrupted atrioventricular compartment. Methods Retrospective analysis of 12 cases of 2: 1 atrioventricular block with interfering atrioventricular disconnection in patients with ECG. The results were similar to those of the third degree atrioventricular block. According to the diagnostic criteria of third degree atrioventricular block, the standard of atrioventricular block was “atrioventricular separation with RR interval> 2 times PP interval, ventricular rate <50 bpm, atrial rate <135 bpm” Can be clearly diagnosed as 2: 1 atrioventricular block with interferential atrioventricular disconnection, junctional escape; associated with ventricular premature beats in 8 cases, 2 cases of atrial premature beats, ST-T changes in 4 cases. Conclusions The atrioventricular block associated with esophageal stroke often complicates the electrocardiogram (ECG), resulting in artifacts that increase the degree of blockage. Misdiagnosis can easily lead to misdiagnosis. A careful analysis of Holter will be helpful for differential diagnosis.
