| 目的 探讨实时三维超声心动图(RT3DE)评价中国东北地区正常新生儿左心室收缩同步性的可行性、准确性及其影响因素。方法 回顾性分析本院接受RT3DE检查的93名中国东北地区的正常新生儿,测量左心室16、12节段和6节段的达最小容积时间的标准差(Tmsv 16-SD、Tmsv 12-SD、Tmsv 6-SD)和最大差值(Tmsv 16-Dif、Tmsv 12-Dif、Tmsv 6-Dif),同时测量心率校正的各参数(%R-R)Tmsv。探讨性别、胎龄、出生体质量和心率对各参数的影响。结果 Tmsv 12-SD与Tmsv 6-SD、Tmsv 12-Dif与Tmsv 6-Dif均高度相关(r=0.76、0.80,P均<0.001);Tmsv 16-Dif与Tmsv 12-Dif中度相关(r=0.47,P<0.001);Tmsv 16-SD与Tmsv 12-SD、Tmsv 16-SD与Tmsv 6-SD、Tmsv 16-Dif与Tmsv 6-Dif弱相关(r=0.27、0.23、0.34,P均<0.05)。性别、胎龄和出生体质量对各参数无影响,心率与Tmsv-SD、Tmsv-Dif呈负相关,对(%R-R)Tmsv无影响。结论 RT3DE方法测量的16节段Tmsv-Dif和Tmsv-SD可全面、准确地评价正常新生儿左心室收缩同步性。 |

| Objective To explore the feasibility, accuracy and its influencing factors of real-time three-dimensional echocardiography (RT3DE) in evaluation of left ventricular (LV) systolic synchrony in northeast China normal newborns.Methods Ninety-three northeast Chinese normal newborns underwent RT3DE were retrospectively analyzed. The standard deviation (Tmsv-SD) and maximal difference (Tmsv-Dif) of the time to the point of minimal regional systolic volume (Tmsv), together with their adjusted parameters by heart rate (%R-R) Tmsv, were calculated from left ventricular 16 segments, 12 segments and 6 segments. Influences of gender, gestational age, birth weight and heart rate on parameters was explored. Results High correlation was observed between Tmsv 12-SD and Tmsv 6-SD, Tmsv 12-Dif and Tmsv 6-Dif, respectively (r=0.76, 0.80, P<0.001);Tmsv 16-Dif had moderately correlation with Tmsv 12-Dif (r=0.47, P<0.001);Weakly correlation was observed between Tmsv 16-SD and Tmsv 12-SD, Tmsv 16-SD and Tmsv 6-SD, Tmsv 16-Dif and Tmsv 6-Dif (r=0.27, 0.23, 0.34, P<0.05). Gender, gestational age and birth weight did not affect on these parameters. Heart rate correlated negatively with Tmsv-SD and Tmsv-Dif, but had no effect on parameters adjusted by R-R interva1. Conclusion Tmsv-Dif and Tmsv-SD measured from 16 segments by RT3DE are useful and reliable parameters for evaluating LV systolic synchrony. |
