经食道心房程序调搏检测房室结双径路——附23例检查报告

本文通过食道心房程序调搏检测出典型房室结双径路23例,其中12例诱发室上性心动过速(占52%);占17例有心动过速发作史者的70.6%。本文着重分析了房室结双径路与室上性心动过速的关系。     

静脉注射维拉帕米或普罗帕酮治疗阵发性室上性心动过速的对比研究

目的观察静脉注射维拉帕米或普罗帕酮治疗阵发性室上性心动过速(PSVT)的疗效.方法静脉注射维拉帕米治疗35例78例次PSVT,并与普罗帕酮治疗31例59例次PSw对比观察.结果维拉帕米组总例次终止率为89.7%,普罗帕酮组总例次终止率为88.7%.两组疗效、终止PSVT发作的心电图形式等无显著性差异(P＞0.05).普罗帕酮组2例较长时间窦性停搏,1例致Ⅲ度房室传导阻滞(AVB),3例中2例死亡.结论房室结折返性心动过速(AVNRT)应用维拉帕米复律优于普罗帕酮(P＜0.05).普罗帕酮副作用较大.     

射频消融治疗室上性心动过速13例报道

目的 :推广应用射频消融治疗快速心律失常。方法 :穿剌动静脉 ,置入刺激和消融电极 ,经多导电生理仪明确消融靶点 ,在局部引入射频电流 ,破坏折返路径。结果 :经电生理检查诊断为室上性心动过速12例 ,特发性室性心动过速1例 ,在20～40W射频功率下经5～200s的放电消融 ,13例均获得成功(成功率100 %)。结论 :射频消融术是治疗室性心动过速 ,室上性心动过速的有效方法 ,且创伤小 ,安全可靠 ,有较高的推广价值     

Radiofrequency ablation in children

Radiofrequency (RF) catheter ablation has ushered in a new era in the management of patients with symptomatic tachyarrhythmias. By providing the ability to cure the underlying arrhythmic substrate, RF catheter ablation obviates the need for life-long antiarrhythmic drugs. In the reported series, the success has been high and the complications have been infrequent and relatively minor. Not unexpectedly, RF catheter ablation has become the treatment of choice for patients with symptomatic paroxysmal tachyarrhythmias. The role of radiofrequency catheter ablation in infants and small children remains controversial, and awaits a larger experience and longer follow-up data.     

Supraventricular arrhythmia: A complication of 5-fluorouracil therapy

5-Fluorouracil is an S-phase-specific, synthetic pyrimidine antimetabolite, which is used as a cytostatic agent for a variety of malignant lesions, either singly or in multidrug regimens. Gastrointestinal toxicity and myelosuppression are the most common adverse reactions, but, of late, clinical cardiotoxicity has been reported in both prospective and retrospective studies. We present our experience of clinical cardiotoxicity in five patients.     

食道心房调搏终止妊娠期室上性心动过速疗效观察

目的：观察经食道心房调搏（TEAP）终止妊娠期阵发性室上性心动过速（PSVT）的临床疗效及安全性。方法：2003年1月～2013年3月收治的51例我院及白银市第一人民医院心内科就诊门诊或住妊娠期PVST患者,TEAP终止发作,观察窦性心律转复率。结果：51例患者TEAP均终止了PSVT发作,转复率100.0%。结论：TEAP转复妊娠期PSVT安全、有效、副反应少,值得在基层医院推广应用。     

射频消融治疗室上性心动过速的疗效

目的研究分析射频消融治疗室上性心动过速的疗效及不良反应。方法回顾性分析我院2009年1月至2011年12月我院收治的52例射频消融治疗室上性心动过速的患者资料,观察患者的治疗效果和不良反应。结果 52例患者成功率为100%,其中旁道参与的室上性心动过速患者28例,成功28例;房室结折返心动过速24例,成功24例。手术后并发症发生1例,随访半年中,有2例复发。结论射频消融治疗室上性心动过速的疗效较好,技术先进,损伤小,手术后不良反应少,复发率低,值得在临床应用。     

硫酸镁治疗室上性快速心律失常

作者用硫酸镁治疗室上性快速心律失常25例,结果:阵发性室上性心动过速10例中6例作终止治疗,4例显效,4例作预防性治疗,3例好转;紊乱性房性心动过速3例于治疗后1小时至2日内纠正;快速房颤4例在治疗后半小时内心室率得到缓解;非阵发性交界区心动过速8例在治疗后10小时至2日内纠正。表明硫酸镁为治疗室上性快速心律失常的一种有效制剂。     

Tratamento de taquicardia supraventricular sincopal durante a gestação sem uso de raios‐X: relato de caso

Arrhythmias during pregnancy pose a dilemma for the treating physician. Most antiarrhythmic drugs are classified as category C in the FDA labeling system during pregnancy. We describe the case of a pregnant woman who presented syncope due to drug‐refractory supraventricular tachycardia who underwent catheter ablation without the use of fluoroscopy.
