目的探讨腹臂导联对于房室传导阻滞的诊断价值。方法选择180例既往心电图疑似房室传导阻滞的患者同步行常规导联和采用胎儿心电图机腹臂导联描记心电图,并进行对比分析。结果⑴腹臂导联心电图P波振幅(6.96±1.31)mm,显著高于常规导联(1.12±0.28)mm;⑵腹臂导联心电图对房室传导阻滞的检出率(70.6%)高于常规导联(51.1%),2组差异有统计学意义(P<0.05)。结论腹臂导联对房室传导阻滞的诊断具有临床实用价值。
Objective To investigate the diagnostic value of abdominal arm leads for atrioventricular block. Methods One hundred and eighty patients with suspected ECG in atrioventricular block were selected to conduct conventional ECG with ECG and ECG with fetal ECG. Results (1) The P-wave amplitude of electrocardiogram was (6.96 ± 1.31) mm in abdominal arm leads, which was significantly higher than that of conventional lead (1.12 ± 0.28) mm; (2) The detection rate of atrioventricular lead ECG on atrioventricular block was 70.6% Higher than the conventional lead (51.1%), the difference between the two groups was statistically significant (P <0.05). Conclusion Abdominal arm leads have clinical value in the diagnosis of atrioventricular block.
