Flatline

For all the times the whumpee's heart stops, no matter if there's a monitor to show it or just someone to say it.

May lead to the classic "Clear!" scene with defibrillators, CPR, caretaker pleading, and many others.

Unless it's the patient of the week on the show, the whumpee rarely dies after.
