His heart was thumping, suddenly, for no reason, as though he had run miles.

Her heart thumped as she walked through into the hall.

Her heart thumped slowly five times before she heard something below.

His heart thumped as he studied the face of the man who sat down at the table.

His heart was thumping, as it had been ever since he'd gotten the news.

He felt cold all over, and his heart was thumping from the shock.

She turned the sound down and listened, her heart thumping too.

Once more, her heart thumping hard, she began to climb.

Somehow, though her heart thumped, she did not feel fear.
