The cardiac electrical impulse normally begins spontaneously in the sinoatrial (SA) node because of what reason?

◦ It has a superior location in the right atrium.
◦ It is the only area of the heart capable of spontaneous depolarization.
◦ It has rich sympathetic innervation via the vagus nerve.
◦ It depolarizes more rapidly than other automatic cells of the heart.
