【摘要】 目的:探讨心电向量图(VCG)诊断左前分支传导阻滞(LAFB)的准确性及临床应用价值。方法:选择心 电图(ECG)诊断为LAFB的住院患者100例,其中男63例,女37例,年龄12～78岁。对其进行VCG检查。结果: 100例中符合VCGLAFB诊断标准者78例,排除22例。检出心肌呈缺血型改变76例,左心室肥大19例,下壁心肌 梗死9例,LAFB合并下壁心肌梗死7例,不完全左束支传导阻滞5例。同一患者可同时存在多种诊断。结论:VCG 诊断LAFB优于ECG。更多还原

【Abstract】 Aim: To ascertain the diagnostic accuracy and clinical efficacy of vector-cardiography(VCG) for diagnosing conduction block in left forearm(LAFB).Methods: A total of 100 patients diagnosed as LAFB by ECG were subjected to perform VCG.The patients included 63 males and 37 females,aging 12~78 years.Results: Only 78 of patients were confirmed as having LAFB complaint.Out of the 78 patients,76 cases were diagnosed as myocardial-ischemia-induced deformation,19 cases as left ventricular hypertrophy,9 cases as myocardial infarction in the lower wall,7 cases as complication of LAFB with myocardial infarction in the lower wall,and 5 cases as incomplete conduction block in left arm.Some suffered from more than one complaint.Conclusion: VCG is superior to ECG in diagnosis of LAFB.更多还原
