目的:运用SPECT门控核素心肌灌注显像(ECG-gated myocardial perfusion SPECT imaging,GSPECT MPI)相位分析技术探讨Wolff-Parkinson-White syndrome(WPW)综合征患者左室机械收缩同步性.方法:入选WPW患者35例和正常对照13例,均行GSPECT MPI检查,其中WPW患者GSPECT MPI检查在导管射频消融(radiofrequency current catheter ablation,RFCA)术前进行,计算出LVEF,MPI数据通过相位分析生成定量指标相位直方图带宽(phase histogram bandwidth,PHB)来评估WPW患者左室机械收缩同步性.根据RFCA术中阻断旁道部位对WPW患者进行分类(间隔旁道组、左侧游离壁旁道组、右侧游离壁旁道组).结果:间隔旁道WPW患者组、左侧游离壁旁道WPW患者组、右侧游离壁旁道WPW患者组、正常对照组LVEF组间比较差异无统计学意义(P>0.05);间隔旁道WPW患者组与正常对照组PHB比较差异有统计学意义(P<0.05),间隔旁道WPW患者存在左室机械收缩不同步,左或右侧游离壁旁道WPW患者组与正常对照组PHB比较差异无统计学意义(P>0.05),左或右侧游离壁旁道WPW患者左室机械收缩不同步不明显.结论:GSPECT MPI相位分析表明间隔部旁道WPW患者存在左室机械收缩不同步.
