WebLeft 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 … WebThis is because the ventricles aren't depolarized simultaneously. If the right bundle branch is blocked, the signal travels normally down the left bundle branch and depolarizes the left ventricle. The right ventricle is then depolarized late as the signal sneaks through a back path while the left ventricle depolarizes. A deformed QRS shape.
WebLeft bundle branch block (LBBB) is a conduction abnormality in the heart that can be seen on an electrocardiogram (ECG). [1] 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 . Causes [ edit] Among the causes of LBBB are: [2] Aortic stenosis WebDec 11, 2024 · Complete left bundle branch block (cLBBB) is associated with increased cardiovascular mortality, sudden cardiac death, and heart failure (Surkova et al., 2024 ). Therefore, the presence of cLBBB on the electrocardiogram (ECG) raises clinical awareness and often warrants further cardiac investigations and clinical follow-up.
