Abstract：Objective To investigate the clinical application value of vectorcardiogram(VCG) in the diagnosis of complete right bundle branch block(CRBBB). Methods A total of 134 patients with CRBBB diagnosed by VCG and ECG were selected and divided into normal cardiac structure group(normal group) and abnormal cardiac structure group(abnormal group) according to the results of cardiac echocardiography. The clinical data and VCG indexes were compared between the two groups. Results Comparison between the two groups reveals that indexes including the abnormal rate of T ring lengthwidth ratio, the abnormal rate of QRS loop voltage to T ring voltage ratio (R/T), QRS loop duration and QRS loop space maximum vector(QRS loop voltage) in the abnormal group are significantly higher than those in the normal group(P＜0.05). However, there is no significant difference in age, gender, body mass index(BMI), QRS loop operating direction and T ring voltage between the two groups(P>0.05). ConclusionT he clinical significance of CRBBB can be preliminarily evaluated combined with VCG analysis indexes.
