bundle branch block

a defect in the specialized conducting tissue of the heart (see arrhythmia) that is recognized as an electrocardiographic abnormality. Left or right bundle branch blocks, affecting the respective ventricles, may be seen. Occasionally both left and right bundle branch blocks occur simultaneously and the patient develops complete heart block. The causes are similar to those of complete heart block.
