rubatosis

n. the unsettling awareness of your own heartbeat, whose tenuous muscular throbbing feels less like a metronome than nervous ditty your heart is tapping to itself, as if to casually remind the outside world, I'm here, I'm here, I'm here.

In music, tempo rubato, "stolen time," is a slight speeding up and slowing down of the tempo of a piece, borrowing time from one measure then paying it back later. Pronounced "roo-bah-toh-sis."
