We reviewed 148 cases of electrical injury admitted to our burn centre. The incidence of persistent vegetative state was 3% (n=5), higher in the low-voltage (6.7%) than in high-voltage group (1.2%). At the time of trauma, 44% (n=65) lost consciousness and 50% of these (n=32) received cardiopulmonary resuscitation on arrival at hospital. Of these, 50% recovered (n=16), 22% became comatose (n=7) and 28% (n=9) died. Of the seven comatose patients, five did not show brain oedema but remained in a persistent vegetative state; this state was more common with low-voltage electrical injuries. The public should be warned of this effect of low-voltage trauma.
Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
