What happens to the left ventricle when the left bundle branch is blocked?
What happens to the left ventricle when the left bundle branch is blocked?
- It becomes electronegative
- It depolarizes more rapidly than the right ventricle
- It remains electropositive (correct)
- It becomes totally depolarized
