室早、室速/室颤常有共同的起源和病理基质,是相互联系与动态演变的统一体。消融与否,不取决于其发病形式,而取决于其病因、症状和预后的严重性。消融方法无固定的模式,应根据病人的具体情况灵活多变,以追求简单、安全、高效和对正常组织损伤最小为原则。目前消融的有效性主要取决于室早/室颤的基础疾病和起源部位。特发与病变局限的室早/室颤,消融效果好,病变广泛或进行性发展的室早/室颤,消融效果有待提高。起源靠近心内膜,尤其是起源于希氏-蒲肯野系统的室早/室颤,容易消融;起源靠近心外膜或心脏的重要结构,如左主干开口,希氏束旁者,消融的难度或风险大。
As early as ventricular tachycardia, ventricular tachycardia / ventricular fibrillation often have a common origin and pathological matrix, is the unity of mutual relations and dynamic evolution. Ablation or not, does not depend on its pathogenesis, but on the etiology, symptoms and prognosis of the seriousness. Ablation method without a fixed pattern, should be flexible according to the patient’s specific circumstances, in pursuit of the simple, safe, efficient and minimal damage to normal tissue principle. The current effectiveness of ablation mainly depends on the premature ventricular / ventricular fibrillation and the origin of the site. Room premature ventricular fibrillation and ventricular fibrillation limitations, ablation effect is good, extensive or progressive disease premature ventricular fibrillation, ventricular fibrillation, ablation effect needs to be improved. Its origins are close to the endocardium, especially premature ventricular / ventricular fibrillation originating from the Hirschprzema system, which is easily ablated; originates close to the important structures of the epicardium or heart such as the left main opening, His bundle, ablation The difficulty or risk.
