摘要 目的:比较心脏标测中单极和双极心内电图的异同。方法:12例因阵发性室上性心动过速接受射频消融手术的患者,多导生理记录仪同步记录窦性心律下体表心电图和冠状静脉窦(CS)单极、双极心内电图(分别为CS1、CS2和CS12、CS23),比较振幅、时限和局部激动时间的异同。结果:单极电图和双极电图的心房A波振幅的差异无明显统计学意义,单极电图的心室(V)波振幅高于双极电图的V波振幅(P<0.05)。单极电图的A波和V波的时限均明显大于双极电图的A波时限(P<0.05)。单极电图和双极电图中局部激动时间的差异无显著性。结论:心脏标测中双极和单极电图的振幅和时限存在一定的差异,两者的联合应用能够提供关于局部激动和远场电位的互相补充的信息。
