Other than the title, The Telltale Head being a play on The Telltale Heart the similarities lie in The Telltale Heart having the narrator, who is presumably the murderer, being haunted by the sound of the victim's beating heart. Bart, who is also the narrator of The Telltale Head briefly, is haunted by the voice of Jebidiah Springfield.
In Edgar Allen Poe's short story "The Telltale Heart", the old man's eye upsets the narrator because he claims to always feel it watching him. This motivation stems from his madness and fuels his actions.
