摘要
目的:对照研究用NOGA^(TM)进行左心室心内膜心肌电机械标测(LVEM)和经胸超声心动图(UCG)对左心室(LV)功能的评估。方法:对15例患者在相同情况下分别行UCG和LVEM检查左心室功能,比较两者在左心室射血分数(LVEF)、左心室每搏量(LVSV)、左心室舒张末期直径(LVDd)以及LV各室壁的运动功能等。结果:UCG和LVEM检查的LVEF、LVSV、LVDd分别为(44.4±7.3)%、(51.3±13.4)ml、(59.1±5.3)mm和(46.1±6.5)%、(53.7±13.6)ml、(60.1±6.1)mm,差异无统计学意义,均P>0·05。结论:UCG和LVEM在检查LV功能上有良好的相关性,LVEM更敏感。
Objective: To evaluate the left ventricular (LV) function by NOGATM left ventricular electromechanieal mapping (LVEM) and compared with ultrasound cardiography (UCG). MethodL:left ventricular ejection fraction (LVEF), left ventrieular stroke volume (LVSV), left ventricular end-diastolic diameter (LVDd) and LV movement of every wall were checked by NOGA system and UCG at same circumstance for 15 patients. Result: LVEF, LVSVand LVDd checked by LVEM and UCGwere (44.4±7.3)%, (51.3±13.4)ml, (59. 1±5.3 ) mm, and (46.1±6.5)%, (53.7±13.6) ml, (60.1±6.1) mm respectively, P〉0. 05, but LVEM is superior to UCG in checking the scar and stunning myocardium. Conclusion: NOGA based global and regional function correlates closely with UCG,but is more sensitive.
