Death from electrical accident due to low voltage (220 Volt/380 Volt) is usually caused by ventricular fibrillation. In humans who sustain non fatal electrical injury abnormal ECG findings due to myocardial damage are rare. 243 (76%) of 320 ECGs of survivors of an electrical accident were diagnosed as normal. In 42 patients (13%) unspecific electrographic changes were seen and in 35 (11%) abnormal ECGs were found. In comparison to findings in normal populations no significant accumulation of ECG changes was observed. A causal relationship between abnormal ECG findings and electrical accident is only then probable if ECG abnormalities are documented immediately after injury and serial ECG controls demonstrate significant changes in comparison to the initial abnormality.
低压（220伏/380伏）电事故导致的死亡通常是由心室颤动引起的。在遭受非致命性电击伤的人群中，因心肌损伤而出现异常心电图表现的情况较为罕见。320例电事故幸存者的心电图中，有243例（76%）被诊断为正常。42例患者（13%）出现非特异性电图改变，35例（11%）发现心电图异常。与正常人群的检查结果相比，未观察到心电图改变的显著聚集现象。只有在受伤后立即记录到心电图异常，并且系列心电图检查显示与初始异常相比有显著变化时，心电图异常与电事故之间才可能存在因果关系。
