Lbbb ECG Explained: See how It affects the heart

Left Bundle Branch Block (LBBB) is a condition identified on an electrocardiogram (ECG) where there's a delay or blockage in the electrical impulses that control the heart's left ventricle. This disruption affects the heart's ability to pump blood efficiently. Normally, electrical signals travel quickly down both the left and right bundle branches, allowing the ventricles to contract simultaneously. However, in LBBB, the pathway for the left ventricle is impaired, causing it to contract later than the right ventricle.

This delayed contraction can lead to a decrease in cardiac output and may be indicative of underlying heart conditions such as hypertension, coronary artery disease, or cardiomyopathy. Symptoms of LBBB can vary from being asymptomatic to experiencing palpitations, dizziness, or heart failure in more severe cases. Diagnosing LBBB is typically done through an ECG, where specific patterns indicate the presence of the block.

Treatment depends on the underlying cause and the severity of symptoms. In some cases, managing the underlying heart condition can alleviate LBBB, while in others, pacemaker implantation might be necessary to ensure proper heart rhythm. Regular monitoring and follow-up with a healthcare provider are crucial for managing this condition effectively.
