The most obvious fault of this paragraph is the lack of punctuation marks. The entire paragraph is one sentence, when there are supposed to be periods, commas, and other punctuation marks to separate them. This makes this paragraph one run-on sentence, which is grammatically incorrect.
The person narrating has committed a murder and shoved the corpse under his floorboards. As some time passes the heart beat is a glimpse into his insanity, and how he is delusional over hearing non existent sounds. He believes he hears the heart of the person he murdered under the floorboards, which is a delusion, most likely made out of paranoia. When the police come to ask about the victim, the man almost fools them until he breaks down and confesses. He expressed annoyance at the victim earlier, saying that he could not get away from their eye, I believe. He tried to solve this by killing them, but his mind would not let him do so by making up false realities.
