“Heart Beat” is a raw, emotional plea for revival and connection, exploring themes of numbness, dependency, and the transformative power of love. The lyrics blend sensual and spiritual imagery, with lines like “Check me for a pulse, baby, I’m dead inside” and “Make my heart beat again” emphasizing the speaker’s desperation for salvation through intimacy.

Musically, the song’s pulsing rhythm mirrors the heartbeat the speaker longs to feel, while the repetition in the chorus amplifies its obsessive, prayer-like quality. Positioned as the third track, it contrasts the seductive tone of “Pornstar” and the fragility of “Aftercare” anchoring the album’s exploration of love’s capacity to heal and resurrect.
