How are the hearts of frogs different from human hearts?

Like humans, frogs have two atria, but they have only one ventricle. The four-chamber human system means that oxygenated and deoxygenated blood remain separate, but in frogs, the blood is mixed when the left and right atria empty into the single ventricle. Does that sound inefficient?

Which is the most primitive animal with a four chambered heart?

The ventricle is divided more effectively by a partial septum, which results in less mixing of oxygenated and deoxygenated blood. Some reptiles (alligators and crocodiles) are the most primitive animals to exhibit a four-chambered heart.
