背景室上性心律失常是住院患者常见的病症并可增加死亡率。房速虽然属于较少见的类型,但对药物反应差,导管消融的成功取决于精准的腔内标测。对于下腔静脉阻塞的患者,由于术者处于非常规的导管操纵位置,如何选择合适的血管径路、保证导管良好的贴靠稳定,都会给成功治疗带来挑战。来自美国旧金山的Kim等报道1例下腔静脉多发性血栓、左上肢动静脉瘘的无休止房 Background Ventricular arrhythmias are a common condition in hospitalized patients and increase mortality. Although atrial tachycardia is a rare type, the poor response to drugs and the success of catheter ablation depend on precise intracavity mapping. For patients with IVC occlusion, the surgeon is challenged with successful treatment because of the unconventional location of the catheter and how to choose the appropriate vascular access to ensure good catheterization and stabilization. Kim et al from San Francisco, USA reported 1 case of multiple inferior vena cava thrombosis, left upper extremity arteriovenous fistula
