Patients may present immediately after the injury or late with cardiac or neurological complications.

Patients with electrical injury should be evaluated as a multiple trauma patient. Airway, breathing, and circulation assessment, and spine immobilisation, should be performed as part of a primary survey. Prior to determining the patient's cardiorespiratory status, the rescuer must first ensure that the danger of further shock has been removed to allow for a safe environment for assessment.[20]
