Heart Pounding From Novocaine

I had my dental work today and everything went well. But, I can't seem to rest right now because my heart is pounding. I had novocaine without epinephrine and I STILL got the pouding. So, my teeth are fine, but I am weak from heart pounding. I can't win!

Is there a chance that your dentist messed up and gave you the novocaine with the epinephrine? That happen to me once.
