Give a stream of consciousness and then the final answer. During the ventricular contraction portion of the cardiac cycle, the Purkinje fibers carry the contraction impulse from both the left and right bundle branch to the myocardium of the ventricles. This causes the muscle tissue of the ventricles to contract and generate force to eject blood out of the heart, either to the pulmonary circulation from the right ventricle or to the systemic circulation from the left ventricle.\n\nThe purkinje fibers are responsible for sending the electrical impulse into which area of the heart?

To answer this question, we should know that: During the ventricular contraction portion of the cardiac cycle, the Purkinje fibers carry the contraction impulse from both the left and right bundle branch to the myocardium of the ventricles.
So, the final answer is the myocardium of the ventricles.
