Electrical injuries induce ventricular arrhythmias, which are lethal. Therefore, it is important to evaluate the risk of arrhythmias at initial presentation to the emergency department in cases of electrical injuries. Here, we report two cases with electrical injuries, where current flowed between the upper limbs, requiring 24-h hospitalization for arrhythmia monitoring. The patients were 57- and 30-year-old men, who sustained separate electrical injuries (6600 V, line voltage), with current flow from one hand to the other. They did not develop any ventricular arrhythmias during hospitalization and were discharged. The risk for ventricular arrhythmias is lower for electrical injuries occurring between the upper limbs than for those occurring between the upper and lower limbs. We conclude that 24-h hospitalization for monitoring of patients with electrical injuries of the upper limbs may be sufficient.
电击伤可诱发致命的室性心律失常。因此，对于电击伤患者，在初次就诊于急诊科时评估心律失常风险非常重要。在此，我们报告两例上肢间有电流通过的电击伤病例，患者因心律失常监测需住院24小时。患者为57岁和30岁男性，分别遭受电击伤（6600V，线电压），电流从一只手流到另一只手。他们在住院期间未发生任何室性心律失常，随后出院。上肢间发生的电击伤导致室性心律失常的风险低于上肢与下肢间发生的电击伤。我们得出结论，上肢电击伤患者住院24小时进行监测可能就足够了。
