Left bundle branch block (LBBB) is a conduction abnormality in the heart that can be seen on an 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. Se mer Among the causes of LBBB are: • Aortic stenosis • Dilated cardiomyopathy • Acute myocardial infarction • Extensive coronary artery disease Se mer LBBB is diagnosed on a 12-lead ECG. In adults, it is seen as wide QRS complexes lasting ≥120ms with characteristic QRS shapes in the Se mer • Bundle branch block • Right bundle branch block • Sgarbossa's criteria Se mer Slow or absent conduction through the left bundle branch means that it takes longer than normal for the left ventricle to fully depolarise. … Se mer • Patients with LBBB require complete cardiac evaluation, and those with LBBB and syncope or near-syncope may require a Se mer
