Quizplus · Accepted Answer

The most likely cause of Jim's congestive heart failure is that the contraction of his left ventricle is not keeping up with the contraction of his right ventricle. This results in a reduced cardiac output and an inadequate blood supply to the lungs, which leads to pulmonary edema and fluid buildup in the lung tissue.
