I liked the sound of her heartbeat up close like this.

She could hear the sound of his heartbeat beneath her ear.

"It was like discovering the sound of your own heartbeat," his friend Penny says.

Here the mother finds the little sick plant that is her child, recognizing it by the sound of its heartbeat.

The sound of her amplified heartbeat ended between one drum beat and the next.

Even the sound of my heartbeat didn't stop me from knowing where she was.

Listen with relief to the strong, steady sound of that internal alien's heartbeat.

There was the sound of her own heartbeat, and the quiet breathing of another.

Hear the sound of her heartbeat in his own ears.

It was quiet as I passed through the kitchen, only the sounds of my heartbeat and a plane high overhead.
