“This was a respiratory arrest, not a cardiac arrest,” Steinberg said.
The hope was that death would occur quickly in an unconscious senseless person both by cardiac and respiratory arrest.
In general, there are two related but distinct physiological ways in which one might die suddenly from a cardiac event.
c.1600, from French cardiaque (14c.) or directly from Latin cardiacus, from Greek kardiakos "pertaining to the heart," from kardia "heart" (see heart (n.)). Cardiac arrest is attested from 1950.
Greek kardia also could mean "stomach" and Latin cardiacus "pertaining to the stomach." This terminology continues somewhat in modern medicine. Confusion of heart and nearby digestive organs also is reflected in Breton kalon "heart," from Old French cauldun "bowels," and English heartburn for "indigestion."
