Her heart, which had leaped at his touch, quieted.

Ryan's storming heart quieted.

My heart quieted.

Weak-kneed, she sat on a smooth slab of stone until her heart quieted in her chest and she could laugh at her own foolishness.

Suddenly her heart quieted, and her breathing eased.

But her heart quieted its frantic beat, for the creature must have sheared off again instead of pressing the attack she had feared from the first.

His heart quieted down, and it seemed like he could think better.

Her heart had quieted and she could hear properly again.

I figured my folks must have thought burglars were trying to break in, but when my heart quieted down I could hear my dad still sawin wood in the bedroom on the first floor.

His heart had quieted now and his shirt felt wet on his chest from the melting snow.
