A delay or block that occurs in one of the bundle branches affects ventricular depolarization
Indicate whether the statement is true or false
T
If a delay or block occurs in one of the bundle branches, the ventricles will not be depolarized at the same time. The electrical impulse travels first down the unblocked branch and stimulates that ventricle. Because of the block, the impulse must then travel from cell to cell through the myocardium, rather than through the normal conduction pathway, to stimulate the other ventricle. The ventricle with the blocked bundle branch is the last to be depolarized.
