Heartbeat Soundtrack

""Can you feel my heartbeat?""

- 2PM, "Heartbeat"

''Thub-thub... thub-thub... thub-thub...''

The human heartbeat is an evocative sound, one with literally life-and-death significance, so it comes as no surprise that songwriters and composers frequently co-opt the sound to inject a little gravitas into a song or a scene.

The beep-beep of an electrocardiogram, or a drumbeat intentionally meant to mimic a heartbeat, also count for our purposes.

When a heartbeat is used in a soundtrack, it's common to partially or completely mute every other sound. The heartbeat then serves either as an indicator that a character is near death, or as an audible indicator of shocked silence.

May overlap with Critical Annoyance in games that use it to symbolize low health. When used properly, it can amount to Paranoia Fuel.
