Left Bundle Branch Block LBBB - normal direction of septal depolarisation is reversed (becomes right to left), as the impulse spreads
What is left bundle branch block? Left bundle branch block (LBBB) occurs when something blocks or disrupts the electrical impulse that causes your heart to beat. This block leads to an abnormal heart rhythm. A diagnosis of left bundle branch block often means that you have an underlying heart condition.
Left bundle branch block (LBBB) occurs when cardiac electrical impulses cannot follow a typical pathway to regulate heart rhythm. It can be a sign of underlying heart disease. Most people with LBBB don't experience symptoms, but some feel breathless or fatigued. If your healthcare provider diagnoses LBBB, treatment such as a pacemaker may be necessary. Lifestyle changes, like eating heart ...

Left bundle branch block (LBBB) is an abnormality in the heart's electrical conduction system. Learn about the seriousness of LBBB and when to worry about life-threatening signs and symptoms.
Left bundle branch block (LBBB) is a cardiac conduction abnormality affecting the heart's electrical system, often requiring specific diagnostic and management approaches.
What Does a Left Bundle Branch Block (LBBB) Mean on an ECG?
Explore LBBB causes, heart vector impact, and ECG findings. Learn about LBBB in leads V1/V6, septal Q waves, ventricular septal infarction, and variants.
Treatment of Left Bundle Branch Block In the absence of underlying heart condition, left bundle branch block does not need treatment. If the LBBB was caused by a heart disease, this disease should be treated.
