There are lots of types of conflict in "The Tell-Tale Heart." Firstly, in the opening of the story, there is an example of man versus self. This is shown when the narrator says that he was "haunted day and night" by the idea of killing the old man. Despite loving the old man, this idea plagues him until he finally relents and decides to commit the murder.
Secondly, there is a man versus man conflict. This takes place between the narrator and the old man and is caused by the latter's "Evil Eye," which the narrator believes is always watching him.
In addition, there is also a man versus society conflict. We see this clearly when the police come to the house after a neighbor reports hearing a "shriek." The narrator's lies form the basis of this conflict: the narrator has no intention of confessing to the murder and lets the police search the house, safe in the knowledge that they will never find the body because it is hidden under the floorboards.
The story closes with a final example of man versus self. Plagued by the noise of a beating heart, the narrator rips up the floorboards to reveal the evidence of his crime.
In the short story, "The Tell-Tale Heart", more than one type of conflict is visible. The conflict between the narrator and the old man illustrates the person vs person type of conflict. The narrator is determined to kill the old man because of his eye. It is also illustrated in a way between the narrator and the reader when the narrator asks, "but why will you say that I am mad?" Person vs self is best seen in the torment the narrator goes through when the police arrive as to whether anyone else can hear the beating of the heart. He debates with himself about what to do, finally giving in and confessing. Person vs society is illustrated between the narrator and the officers of the law because the narrator knows that he will be arrested if the heart is found. Each of these conflicts is clearly found in the story.
The types of conflict that are present in Edgar Allan Poe's short story, "The Tell-Tale Heart" are person vs. self and person vs. person. The protagonist, a care taker of an old man is annoyed and dsitrubed by the eye of the old man. He claims that the eye is possessed by evil, calling it the "Evil Eye". He leads out a plan to go and kill the man. The person vs. self, is the protagonist vs. himself. His own conscious is the sound of the heartbeat. He is hearing the guiltiness.
