flat line

No pulse detected

A flat line is a horizontal line on a monitor or graph showing no variation—especially the continuous tone on a heart monitor indicating death.

To flatline is to die or, figuratively, to stall completely: The project flatlined after funding was cut.

Also spelled as one word: flatline.
