Right bundle branch block is a more benign arrhythmia than left bundle branch block, but it can lead to dyspnea, palpitations, or chest pain. Therefore, it is necessary to have a proper treatment and rest regimen.

Left bundle branch block is a condition in which the impulse cannot be transmitted to the left atrioventricular bundle, so the impulse will go to the right atrioventricular bundle to depolarize the right ventricle first, then conduction to the left to depolarize the left ventricle.
