急性心肌梗塞(AMI)具有较高的病死率,心室颤动为主要死亡原因之一。抗心律失常治疗的各种方案包括选择性治疗“警告性心律失常”,非选择性地对所有疑似急性心肌梗塞病人预防用药以及仅治疗心室颤动和具有血流动力学改变的心律失常。在美国,对大多数疑似急性心肌梗塞病人应用利多卡因预防原发性心室颤动;而在欧洲,主要采取迅速处理心室颤动和选择性地预防用药。对这些不同的处理方案尚没有一个比较满意的
Acute myocardial infarction (AMI) has a high case fatality rate, and ventricular fibrillation is one of the major causes of death. Various options for antiarrhythmic therapy include selective treatment of “warning arrhythmias”, non-selective prophylaxis in all patients with suspected acute myocardial infarction, and arrhythmia that treats only ventricular fibrillation and has hemodynamic changes. In the United States, lidocaine is used to prevent primary ventricular fibrillation in most patients with suspected acute myocardial infarction; in Europe, the primary treatment is rapid ventricular fibrillation and selective prophylaxis. There is not yet a satisfactory one for these different treatment options
