As pulmonary fibrosis worsens, you become progressively more short of breath. This reduces blood flow to the right bundle branches, which are the special fibers that carry the electrical signals from the right atrium to the right ventricle. It indicates that the hearts electrical impulse is not being distributed normally across the ventricles, the chambers that pump blood out of the heart.
