Persona 4 is the 2008 role playing game from Atlus, later expanded as Persona 4 Golden and adapted into anime, following students investigating murders in the rural town of Inaba. Its tense investigation and dungeon scenes helped make simple tension cues like a heartbeat easy for fans to recognise. Clips of the game's sound effects have since circulated on soundboards and in fan edits, where this heartbeat is reused far beyond the original game as a quick audio shorthand for fear, stress and impending danger in memes and videos.
