Which of the following is a characteristic of left bundle branch block?
A)The right ventricle depolarizes normally, but conduction through the left ventricle is slowed.
B)The left ventricle depolarizes normally, but the impulse is not spread to the right ventricle.
C)Neither ventricle depolarizes normally because the impulse is not conducted through the left bundle branch.
D)Neither ventricle depolarizes normally because the impulse is not conducted through the right bundle branch.

In left bundle branch block (LBBB), the electrical impulse that normally travels down the left bundle branch is delayed or blocked. This means that the right ventricle depolarizes normally through the right bundle branch, but the conduction through the left ventricle is slowed, leading to a delay in the depolarization of the left ventricle.
