My Heart, New Heart

They gave me a tablet that tasted foul,
Then an injection that made me howl,
The nurse and doctor put me to sleep,
Then I knew that my heart was not for keeps.
There was a bright light above my head,
and the plate-like contraption was painted red.
The machine finger prodding suddenly got sharp,
The fingers were twining my veins like a harp,
The metal plate now pushed through,
Though there was no blood or fatty goo.
Finally the plate found my heart,
And slowly and hesitantly tore it apart.
Now the plate is my new heart,
And instead of me dying,
It gave me a new start.
