Abstract:
The occurrence of ventricular tachycardia (VT) in patients with acute myocardial infarction (AMI) is associated with poor prognosis. Drug therapy and implantable cardioverter-defibrillators (ICDs) are effective methods to prevent sudden death. Radiofrequency (RF) catheter ablation can map the matrix and mechanism of VT, thereby effectively reducing the occurrence of ICD discharge. This paper reports on the case of a middle-aged man who underwent emergency percutaneous coronary intervention for AMI and developed VT and ventricular fibrillation on day 7 after reperfusion. An ICD was implanted. On day 19, he received catheter ablation because of refractory monomorphic ventricular tachycardia and frequent discharge of the ICD. After three months, the patient had not experienced any further ventricular tachycardia attacks. The conclusion is that RF catheter ablation can resolve the ES after myocardial infarction and significantly reduce the occurrence of ICD discharges.
摘要:
急性心肌梗死(AMI)患者室性心动过速(VT)的发生与预后不良有关。药物治疗和植入式心脏复律除颤器(ICD)是预防猝死的有效方法。射频(RF)导管消融可以绘制VT的矩阵和机制,从而有效减少ICD放电的发生。本文报道1例中年男子因AMI行急诊经皮冠状动脉介入治疗,并在再灌注后第7天发生VT和心室纤颤。植入了ICD。在第19天,由于难治性单形性室性心动过速和ICD频繁出院,他接受了导管消融。三个月后,患者没有出现任何进一步的室性心动过速发作.结论射频导管消融术可以解决心肌梗死后的ES,并显着减少ICD放电的发生。
