Causes of RBBB. 1  Right ventricular hypertrophy / cor pulmonale. 2  Pulmonary embolus. 3  Ischaemic heart disease.  Rheumatic heart 1  disease. Myocarditis or cardiomyopathy.  Degenerative disease of the conduction 1  system. Congenital heart disease (e.g. atrial septal defect)
Left bundle branch block (LBBB) is a cardiac conduction abnormality seen on the electrocardiogram (ECG). In this condition, activation of the left ventricle of the heart is delayed, which causes the left ventricle to contract later than the right ventricle.
