If you have a bundle branch block, it may cause a glitch in the electrical impulses that make your heart beat.

Left bundle branch block is a condition in which there's slowing along the electrical pathway to your heart's left ventricle.

However, unlike in the presence of a left bundle branch block, myocardial ischemia and infarction can easily be detected on ECG when a RBBB is present (see anterior and inferior wall MI examples).

A left bundle branch block occurs when electrical conduction is unable to course through the left bundle and instead travels down the right bundle.

Those who have left bundle branch block can also experience symptoms such as pre faint condition in which people feel like fainting but they actually don’t.

The left ventricle pumps oxygen-rich blood throughout the body. The pathway that leads to the right ventricle is called the right bundle branch.

In addition, the type of bundle branch block also matters. If it is a right bundle branch block (RBBB) and you have no symptoms, usually there is nothing else you need to do.

Did you know that certain medications can cause symptom of 'Right Bundle Branch Block'. Find these drugs listed on the page and be warned of similar symptoms as possible side-effects.

Q. Please explain a bundle-branch block on the left side of my heart. Cause? Cure? Complications? After viewing my EKG, my anesthesiologist referred to the condition as a heart abnormality and sugg… ...

No new left bundle branch block occurred after hospital discharge. In multivariate analysis, predictors of persistent left bundle branch block were greater ventricular depth of valve implantation and ...

Instead, the impulse travels cell-to-cell, using the impulses from the right bundle. Fortunately, in a person with a bundle branch block and no symptoms, the risks are small.

A left bundle branch block is a type of disruption of the heart's electrical impulses that can signal an underlying heart condition. Learn more here.
