Abstract

A patient with episodes of palpitation in whom the electrocardiogram showed a right bundle branch (RBBB) configuration and right axis deviation underwent electrophysiologic study and radiofrequency ablation. Left ventricular endocardial mapping during ventricular tachycardia (VT) identified the earliest ventricular activation in the anterolateral wall of the left ventricle. The fused Purkinje potential was recorded at that site, and preceded the QRS complex by 47 mseg, with pace mapping showing an optimal match between the paced rhythm and the clinical VT. The stimulus to QRS time was equal to the Purkinje potential-QRS time. Several radiofrequency lesions were applied in this region, one of them resulted with termination of the tachycardia. Following delivery of this lesion the ventricular tachycardia couldn't be induced either at baseline or during isoproterenol infusion. During VT, atrial fibrillation and atrial flutter were observed, cardioversion was performed reverting to sinus rhythm.

双速性心律失常:左前束性室性心动过速伴心房扑动和颤动。病例报告]。

心悸发作的患者，心电图显示右束支(RBBB)结构和右轴偏离，接受电生理研究和射频消融。室性心动过速(VT)时的左室心内膜测图确定了左室前外壁最早的心室激活。在该部位记录融合浦肯野电位，比QRS复合体早47 mseg，起搏图显示有节奏节律和临床VT之间的最佳匹配。QRS时间的刺激等于浦肯野电位-QRS时间。在该区域应用了几个射频病变，其中一个导致了心动过速的终止。在该病灶娩出后，在基线或异丙肾上腺素输注期间均不能诱发室性心动过速。室性心动过速期间，观察到心房颤动和心房扑动，进行复律恢复窦性心律。
