尖端扭转型室速(TDP)发生室颤及死亡率高。本文报告7例本症患者,其中3例单用药物得到控制.4例经紧急心内膜临时起搏,3例成功,1例电极未到位 例1室扑、室颤发作18次,13次自行转变为TDP,5次经电转复为窦律,起搏控制TDP后发生持续低血压状态,经多巴酚丁胺及大剂量参脉液等治愈。例2因电极头仅到右房,起搏不能控制TDP而死亡。例3电转及临时起搏完全控制TDP,后因Ⅲ°AVB不能恢复最终安置永久起搏器。例4 TDP发作23小时最终经起搏完全控制。例5在27小时内阿-斯发作8次,因当时技术原因不能起搏而每次发作用异丙肾素
Torsades de pointes (TDP) causes high ventricular fibrillation and mortality. This article reports 7 patients with this disease, of which 3 were controlled by drugs alone .4 cases of emergency endocardial pacing, 3 cases of success, 1 case of the electrode is not in place, 1 room flutter, ventricular fibrillation attack 18 times, 13 times Self-transformation into TDP, 5 times by electrical conversion to sinus rhythm, pacing control after TDP sustained hypotension, after dobutamine and high-dose paracentesis and other cured. Example 2 because the electrode only to the right atrium, pacing can not control TDP and died. Example 3 electrotransport and temporary pacing complete control of TDP, because after the third ° AVB can not be restored final placement of permanent pacemaker. Example 4 TDP onset 23 hours eventually controlled by pacing. Example 5 In 27 hours, A - Si attack eight times, because of the technical reasons can not be pacing and each onset of isoproterenol
