Answer:
(1) The pressure of guilt, (2) sanity and madness, and (3) the passage of time are Dassin and Hougs' themes. The meaning is that sanity is something we need to maintain and guilt is a powerful thing.
I think this because the dead person’s beating heart is a manifestation of the narrator's guilt towards killing him. In addition, the narrator's attempts to prove his sanity by explaining his carefully thought-out plans just made him sound more insane and proved his madness. Lastly, the narrator's recurring references to time emphasize the relationship between time and the mind, as well as its impact on the psyche.
To conclude, this new meaning matters because it tells us important things. Though, to summarize my points, the narrator has conflict with the man and his own psyche, which led to the killing of the man and the guilt consuming the narrator along with the rest of his sanity.
