随着心房颤动导管消融治疗的日益广泛开展,导管消融术后快速性房性心律失常(即继发性房性心律失常,包括房性心动过速和心房扑动)逐渐成为临床心律失常治疗的关注热点,其机制在不同患者中不尽相同,甚至同一患者亦可涉及多种机制,因此这种心律失常的处理可能较心房颤动本身更为棘手。现就心房颤动导管消融术后发生快速性房性心律失常的可能机制及其防治策略作一综述。
With the increasingly widespread use of catheter ablation of atrial fibrillation, rapid atrial arrhythmias (ie, secondary atrial arrhythmias, including atrial tachycardia and atrial flutter) after catheter ablation have gradually become clinically arrhythmic Focus on hot spots, the mechanism varies in different patients, and even the same patient can also involve a variety of mechanisms, so the treatment of arrhythmia may be more difficult than the atrial fibrillation itself. Now on the atrial fibrillation catheter ablation after the occurrence of atrial tachyarrhythmia possible mechanism and prevention and treatment are reviewed.
