右室双部位起搏临床应用的探讨

证实右室双部位起搏的临床疗效和置入方法的可行性。 4例因不同原因的心脏病合并严重心律失常、心功能不全。包括 2例患者已埋置永久心脏起搏器 (VVI) 2～ 4年 ,术后心功能减退 ,心律失常未获纠正的患者改行右室双部位起搏。 4例患者术后心功能及起搏器综合征明显改善 ,原已存在的心律失常得以纠正。认为右室双部位起搏简单、易操作、不增加埋置术危险度等优点 ,临床疗效明显 ,可作为双室同步起搏的另一种起搏方式在临床应用。

TheStudy of Clinical Application of Pacing at Dual Sites of Right Ventricule

To identify the clinical efficacy of pacing at dual sites of right ventricule and the feasibility of its implantation.4 patients with different causes of cardiac diseases complicated with serious arrhythmias and heart failure, including 2 cases with heart failure and arrhythmias after implanted permanent cardiac pacemaker (VVI) 2-4 years were accepted pacing at dual sites of right ventricule. Cardiac function and the pacemaker syndrome were improved significantly as well as arrhythmias being controlled after implantation. We concluded that pacing at dual sites of right ventricule has some advantage such as pacing and operating easily without increasing the risk of implantation, its clinical efficacy is so high that it can be widespread accepted as an indirect form of synchronous dual ventricular pacing.
