heart-stopping

She looked up again, and this time his heart did stop.

Always she looked at me with her big brown eyes and my heart stopped.

My heart almost stopped as the sense of the words came through.

Every time he saw her about the house it was as if his heart stopped.

My heart stopped, for I knew it was news of some sort.

Her heart almost stopped with the pain of having him so near.

If I'd had one, my heart probably would have stopped at that.

No one here would be able to tell anything except that his heart stopped.

Breath and heart could not have stopped very long ago.

He felt her fingers close around him and thought his heart might stop.
