Electrical injury can cause cardiac problems and various electrocardiographic (ECG) changes. It has been suggested that an electrical current may permanently damage the cardiac conduction tissue and predispose to late dysrhythmia. Less serious transient ECG changes have also been described after electrical injury, such as ST segment elevation. Electrical injuries can cause delayed cardiac problems. In the emergency department, a patient who has chest pain and ECG changes should be investigated through his history about any previous electrical injury, so that we can differentiate myocardial infarction and other cardiac problems mimicking it.
