完全性右束支阻滞QRS平均电轴变化的临床意义

Clinical Significance of Changes in Everage Electric Axis in CRBBB

目的 :探讨完全性右束支阻滞 (CRBBB) QRS平均电轴的意义。方法 :采用 Kenz- cardico12 0 3型 12导 ECG描记15 2例 CRBBB的 QRS。分析全组的平均心电轴改变。结果 :电轴右偏以风心病、肺心病、先心病多见 ,电轴左偏以冠心病、高血压病多见 ,电轴正常以正常人多见。结论 :在 CRBBB时 ,电轴右偏 >+ 110度 ,左偏 <- 30度有器质性心脏病的可能。

Aim:To investigate the clinical significance of changes in everage electric axis in complete right bondle branch block(CRBBB),Methods:ECG of 152 patients with CRBBB were examined with eletrocardiograph (Modle 1203 kenz cardico) and the everages of eletric axis were analyzed.Results:Right axis deviation was observed more in cases of rheumatic valvalar heart disease,chronic pulmonary heart disease and congenital heart disease;and left axis deviation was found more in those with coronary heart disease and hypertension.A normal electric axis was usually seen in the normal subjects.Conclusion:Organic heart disease may be confirmed when right axis deviation is larger than 110° or left axis deviation reaches -30°。
