Commotio cordis may occur also in other situations, such as in children
who are punished with blows over the precordium, cases of torture,
frontal collisions of motor vehicles (the impact of the steering wheel against
the thorax, although this has decreased substantially with the use of safety belts and air bags).
Cases of commotio cordis have been recorded in people who were shot by
firearms over the precordium and were using body armour,
[2] thus stopping the bullet but causing a mechanical impact to the thorax
(the so-called Behind Armour Blunt Trauma or BABT); or after being hit by
less-lethal crowd control firearm shots using rubber bullets or plastic bullets.[3]
