Question

Quizplus · Accepted Answer

Sympathetic stimulation of the heart increases heart rate (A), decreases the duration of systole (B), increases the amount of calcium ion entering cardiac cells (D), and increases the rate of cross-bridge cycling in ventricular cells (E). However, it does not decrease the slope of the pacemaker potential (C). In fact, sympathetic stimulation enhances the slope of the pacemaker potential, leading to a faster depolarization and higher heart rate.
