Define this statement as standard, slang, jargon, dialect, or ungrammatical. the myocardial infarction resulted in the transposition of nerve impulses

This statement is jargon, and jargon is the language used by certain professions, such as lawyers, doctors, etc.
So having this in mind, we can see that the sentence clearly used medical terms, so it has to be jargon. 

If you give me the two excerpts to compare, i would be able to you : )
