Quizplus · Accepted Answer

Cardiac output is determined by the heart rate and stroke volume. An increase in sympathetic stimulation can increase the heart rate, which in turn would increase cardiac output. Increased end-diastolic volume can lead to increased stroke volume, which would also increase cardiac output. Therefore, all of the choices (A, B, and C) are correct.
