The suddenly rapid beating got her attention like a loud knock at the door.

He could almost hear the rapid beating of her heart.

At the same time I was aware of the rapid beating of my heart.

Haplo was still trying to calm the rapid beating of his heart.

He could feel the rapid beating of the beast's heart and that made his own heart beat less rapidly.

It was the rapid beating of a tiny heart.

Neither spoke for a moment, and in the silence the rapid beating of two hearts was heard.

His palm engulfed the rapid beating of her heart.
