Reciprocating tachycardia during central venous cannulation in a patient with Wolff-Parkinson-White syndrome

Wolff-Parkinson-White syndrome is important for the anesthesiologist because the sudden development of tachyarrhythmias may result in deleterious hemodynamic changes. We describe an episode of reciprocating tachycardia triggered by the insertion of the guide wire during central venous cannulation in a patient with this syndrome.     

三腔ICD临床应用5例报告

目的三腔ICD治疗5例心衰同时合并室性心动过速结果分析.方法应用三腔ICD治疗5例心衰同时合并室性心动过速(简称室速)患者,4例为原发性扩张型心脏病,1例为冠心病,2例有昏厥史.4例植入INSYNC 7272埋藏式心脏转复除颤器(ICD),1例植入V-350 ICD.结果随访时间1~14月,心功能得到改善,未发生室速,均未发生昏厥.5例中1例出现室性心动过速和心室颤动发作(简称室颤)均被ICD识别并进行放电除颤治疗,挽救了患者的生命.结论三腔ICD是治疗猝死、致死性心律失常和心衰的有效措施.     

导管射频消融治疗严重症状性室性早搏的初步研究

目的:探索导管射频消融治疗严重症状性室性早搏(室早)伴或不伴室早诱发的短阵室性心动过速(室速)的安全性、效率和方法学。方法:18例严重症状性室早患者入选本研究,术前室早数量平均(117±37)次/h。术前根据同步12导联体表心电图初步推测室性早搏产生部位,术中依据初步推测的室早产生部位采用心室激动顺序标测法与起搏标测法进行室早标测定位,大头消融电极标测到室早最早激动点较体表心电图QRS波提前25ms以上或消融电极起搏心电图QRS波图形与室早图形11/12以上一致时放电消融。结果:18例患者导管射频消融即时成功16例,术后室早数(6±2)次/h,较术前显著减少(P<0.05);随访12个月,18例中16例消融成功,成功率88.9%;无严重并发症发生。结论:导管射频消融治疗严重症状性室早伴或不伴室早诱发的短阵室速安全、有效,同步12导联体表心电图对室早的定位有重要的指导意义。     

射频消融治疗快速型心律失常951例临床分析

目的分析总结经导管射频消融治疗快速型心律失常的疗效,以进一步指导相关临床工作。方法回顾性分析951例(男532例,女419例)经导管射频消融治疗快速型心律失常患者的治疗结果,患者年龄6~78(42.5±14.6)岁,心动过速发作史1个月~42年,采用常规方法进行电生理检查和射频消融。结果房室折返性心动过速(AVRT)569例,计有旁道578条,其中左侧旁道患者462例(分布位置:左游离壁364例,左前壁41例,左后侧壁57例),右侧旁道79例,双旁道9例(右侧6例,左侧3例),房室结双径路合并房室旁道19例(右侧5例,左侧14例)。房室结折返性心动过速(AVNRT)341例,其中260例存在前向跳跃式传导,16例存在逆向跳跃式传导,65例无跳跃式传导。室性心动过速(VT)19例,房性心动过速(AT)22例。射频消融总成功率为97.9%,其中房室结双径路和左侧房室旁道介导的阵发性室上速射频消融成功率高达99.5%。射频消融术后复发率为1.7%。8例术中出现一过性房室传导阻滞,后有2例发生Ⅰ度房室传导阻滞,1例交替出现Ⅰ、Ⅱ、Ⅲ度房室传导阻滞,1例发生Ⅲ度房室传导阻滞后置入永久性心脏起搏器;术后12例发生假性动脉瘤,1例气胸和1例心包填塞。结论经导管射频消融是治疗快速型心律失常安全有效的方法,尤以AVRT和AVNRT的效果最佳。     

False Tendon‐Related Polymorphic Ventricular Tachycardia

A 39‐year‐old woman showed nonsustained polymorphic ventricular tachycardia (PVT) during light physical activity. Cardiac multidetector row computed tomography demonstrated false tendons, one of which proved to be the focus triggering premature ventricular contraction (PVC) in electrophysiological studies. The triggered PVC arose during the diastolic period, which might have caused tension in the false tendon. Radiofrequency catheter ablation targeting the triggered PVC by pace mapping was performed and proved partially effective against PVT. (PACE 2012;35:e341–e344)     

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.
