Clinical significance of complete left bundle branch block in dilated cardiomyopathy.

Author information

Department of Cardiology, Rui Jin Hospital, Shanghai Second Medical University.


Clinical, electrocardiographic and echocardiographic findings in 64 patients with dilated cardiomyopathy were restrospectively studied. Compared with 51 patients without complete left bundle branch block (CLBBB), 13 patients with CLBBB had higher New York Heart Association (NYHA) functional class (P < 0.05), increased left ventricular end-diastolic and end-systolic diameters (P < 0.002) and myocardial mass (P < 0.02), severe mitral regurgitation (P < 0.01) and higher mortality rate (P < 0.04). Multivariate stepwise regression analysis revealed that the presence of CLBBB was an independent prognostic factor for patients with dilated cardiomyopathy.
