解析

Radiofrequency /,reidiəu-'fri:kwənsi/ 

释义   n. 高频,射频;高周波

例句   Radiofrequency ablation, sometimes referred to as RFA, is a minimally invasive treatment for cancer. It is an image-guided technique that heats and destroys cancer cells. 射频消融术,缩写为RFA,是一种针对癌症的微创疗法。它是一种通过导航技术找到并加热杀死癌细胞的技术。

 

Catheter 英 /'kæθɪtə/美 /'kæθɪtɚ/ 

释义   n. [医] 导管;导尿管;尿液管

例句   Objective: To Select fixation method of PICC catheter for prevent infection effectively by restricting PICC catheters movement in the body. 选择PICC导管牢固的固定方法,以达到限制导管自由进出体内有效地预防感染的目的。

 

Ablation 英 /ə'bleɪʃ(ə)n/  美 /ə'bleʃən/

释义   n. [水文] 消融;切除

例句   However the energy and efficacy of ablation remain the major factors restricting the success rate. 然而,消融的能量和效能仍然是制约成功率的主要因素。

Pharmacologic therapy of arrhythmias, while frequently effective, is limited by high failure rates, potential for proarrhythmia, and drug toxicity. Nonpharmacologic therapy for symptomatic and life-threatening cardiac arrhythmias includes the use of catheter ablation, the implantable cardioverter-defibrillator for ventricular arrhythmias, and, at times, cardiac surgery. The clinical role of catheter ablation in the treatment of arrhythmias will be reviewed here. A discussion of invasive cardiac electrophysiology studies and cardiac mapping, both precursors to catheter ablation, is presented separately.Catheter ablation either using radiofrequency or cryothermal energy has emerged as a major tool for the non-pharmacological management of the vast majority of arrhythmias that are refractory to antiarrhythmic drug therapy for arrhythmias that are symptomatic and/or may have an untoward effect on cardiac function.In most supraventricular tachycardias (atrioventricular reentrant tachycardia [AVRT] or AV nodal reentrant tachycardia [AVNRT], in atrial flutter, and in macroreentrant or focal atrial tachycardias) and in idiopathic ventricular ectopy/tachycardia, the success rates are high. Catheter ablation of atrial fibrillation is increasingly offered to drug-refractory symptomatic patients with paroxysmal tachycardia and selected patients with persistent atrial fibrillation with the aim of isolating the pulmonary vein where most ectopic foci are located and/or to modify the anatomic left atrial substrate ,For life-threatening ventricular tachyarrhythmias (ventricular tachycardias and ventricular fibrillation), the mainstay treatment is the implantable cardioverter-defibrillator (ICD) alone or in combination of pharmacological therapy for the prevention of arrhythmia episodes. Catheter ablation may be useful in reducing the frequency of appropriate ICD discharges and to improve patient quality of life or to treat the arrhythmia storm in patients with ICD.

心律失常的药物治疗虽然经常有效,但受到高失败率,致心律失常的可能性和药物毒性的限制。针对有症状和危及生命的心律失常的非药物治疗包括使用导管消融,植入式心律转复除颤器用于室性心律失常,以及有时进行心脏手术。这里将回顾导管消融治疗心律失常的临床作用。关于侵入性心脏电生理学研究和心脏标测的讨论,两者都是导管消融的前体,单独列出。使用射频或低温能量的导管消融已成为绝大多数心律失常的非药物治疗的主要工具,所述心律失常对抗心律失常药物治疗难以治疗,所述心律失常是有症状的和/或可能对心脏功能具有不良影响。在大多数室上性心动过速(房室折返性心动过速[AVRT]或房室结折返性心动过速[AVNRT],心房扑动,大房性或局灶性房性心动过速)和特发性心室异位/心动过速中,成功率很高。心房颤动的导管消融越来越多地用于阵发性心动过速的药物难治性症状患者和选择的持续性心房颤动患者,其目的是分离大多数异位病灶所在的肺静脉和/或改变解剖学左心房基质,对于危及生命的室性快速性心律失常(室性心动过速和心室颤动),主要治疗方法是单独使用植入式心律转复除颤器(ICD)或联合用于预防心律失常发作的药物治疗。导管消融可用于降低适当ICD放电的频率并改善患者的生活质量或治疗ICD患者的心律失常风暴。
