I could hear someone taking the phone from her as my heart hammered.

My heart was hammering, though for the life of me I could not have said why.

I went there and my heart was hammering within me.

By the time he reached the door, his heart was hammering.

Her heart hammered so hard she could barely hear herself speak.

While her heart hammered she turned to watch him come out of the shadows.

Her heart was hammering so hard, she could barely think straight.

Her heart was hammering like a drum, yet being in his arms seemed quite natural.

Her heart was hammering so loudly she thought he might hear it.

Her heart hammering painfully, she took a step toward him.
