Nerve impulses are still firing after the heart has been removed. The cardiac muscles that make up the heart of a frog is filled with nerve cells. The same phenomenon is common with fish as well. Essentially the body still has reserves of sodium ions that still trigger the sodium pumps of the axons to fire, creating the twitch.

when muscles (like the heart) are contracting, they are releasing heat, which keeps the electrochemical reactions in the muscles going - so the muscles keep contracting. after a frog (or any other animal) is freshly killed, the frog's muscles still have heat, so they still continue to contract for a little while even after the muscles have been removed from the body. eventually, after the heat dissipates, the muscles stop contracting.

if the heart is still connected and not severed it will still beat,until all the blood is pumped out of it,much like a human heart.
During open heart surgery on humans,hearts on sometimes placed outside the body and then returned in its place.
