左前分支型左束支阻滞的心电向量图特征(附4例分析)
Vectorcardiographic features of left anterior fascicular block-type left bundle branch block:analysis of 4 cases
摘要
Abstract
Using a stereoelectrocardiograph,electrocardiogram(ECG)and vectorcardiogram(VCG)were synchronously recorded via the Wilson and Frank dual-lead systems to timely detect and diagnose left anterior fascicular block-type left bundle branch block(LAFB-type LBBB).Cases with clinical manifestations and clearly diagnosed LAFB-type LBBB based on VCG were selected for analysis.In four cases of LAFB-type LBBB,the VCG manifestations showed features of LAFB in the frontal plane and complete LBBB in the horizontal plane.VCG was significantly superior to ECG in diagnosing LAFB-type LBBB.Regardless of the version of ECG diagnostic criteria for LAFB-type LBBB,the diagnostic reliability of ECG remains limited without the verification of VCG.Therefore,clinicians should be cautious in diagnosing LAFB-type LBBB using ECG alone.In practical work,ECG and VCG should complement each other by leveraging their respective strengths to jointly serve clinical practice.Combining the two methods can improve diagnostic accuracy.关键词
