I heard it this morning on the radio

I heard nothing of it until ten minutes ago

I've heard your name before.

He heard the bad news without batting an eyelid

I heard you on the phone.

I heard someone knocking on the door.

I heard you singing.

I heard it from him.

I heard it through the grapevine

I heard a call for help.

Hearing a person as a witness in support of his own case is problematic

heart is in the right place

heart rending

heart throb

My heart was never really in it

by heart

My heart goes out to you

My heart sank/went into my boots

My heart bleeds for her/him!

at heart

At heart I am a good man.

My heart was full of joy when I saw you.

My heart bleeds

My heart missed a beat

My heart sank
