Asystole
Asystole (New Latin, from Greek privative a "not, without" + systolē "contraction" ) is the absence of ventricular contractions in the context of a lethal heart arrhythmia (in contrast to an induced asystole on a cooled patient on a heart-lung machine and general anesthesia during surgery necessitating stopping the heart).
