起搏标测已被用于识别局灶性室性心律失常的起源部位。起搏标测的空间分辨率尚未充分量化使用目前可用的三维mapping systems. ObjectiveThe目的本研究的目的是确定起搏标测的空间分辨率的特发性室性心动过速或室性早搏起源于右心室流出道的患者。由两个观察者进行起搏图的比较和分类（良好起搏图：匹配> 10/12导联;不适当起搏图：匹配：
BACKGROUND Pace mapping has been used to identify the site of origin of focal ventricular arrhythmias. The spatial resolution of pace mapping has not been adequately quantified using currently available three-dimensional mapping systems.OBJECTIVE The purpose of this study was to determine the spatial resolution of pace mapping in patients with idiopathic ventricular tachycardia or premature ventricular contractions originating in the right ventricular outflow tract.METHODS In 16 patients with idiopathic ventricular tachycardia/ectopy from the right ventricular outflow tract, comparisons and classifications of pace maps were performed by two observers (good pace map: match > 10/12 leads; inadequate pace map: match :
