Radiofrequency catheter modification of the sinus node for persistent inappropriate sinus tachycardia has not been previously reported. This article describes a patient in whom radiofrequency current was used to ablate an incessant automatic tachycardia focus mapped to the region of the sinus node, where a discrete multicomponent electrogram demonstrating earliest atrial activation was recorded. A transient junctional rhythm developed immediately after ablation, with rapid subsequent emergence of a stable rhythm having normal sinus nodal characteristics.
射频导管改良窦房结治疗持续性不适当窦性心动过速此前未见报道。本文描述了一名患者,使用射频电流消融映射至窦房结区域的持续性自动性心动过速病灶,在此记录到显示最早心房激动的离散多成分电图。消融后立即出现短暂的交界性心律,随后迅速出现具有正常窦房结特征的稳定心律。
