The word latidos means heartbeats in Spanish, and this clip is a straightforward recording-style heartbeat loop rather than a line from a film or game. Heartbeat sounds have long been used in horror, thrillers and dramatic videos because the body recognises the rhythm instantly, and creators on short-form platforms have adopted the same trick for tension edits, pranks and reaction clips. Its simple, looping pulse makes it easy to drop under almost any scene, which is why it continues to appear in suspense edits, gaming videos and jumpscare content.
