摘要
测量人心脏室间隔膜部厚度随胎儿宫内年龄沿一条陡峭、上升的直线增加。PMSI增厚发生在开发的第一阶段，从0.246 mm (CR = 16.8 mm)到0.524 mm (CR = 119 mm)，在第二阶段从0.601 mm (CR = 149 mm)到1.024 mm (CR = 362 mm)。然后，从第二室间孔闭合结束到胎儿期结束，厚度增加。
Development of the pars membranacea septi interventricularis of the human heart. II. Thickness change.
The measurement of the thickness of the pars membranacea septi interventricularis of the human heart increases with the intra-uterine age of the fetus along a steep, ascending, straight line. The thickening of the PMSI occurs in phase I of the development from 0.246 mm (CR = 16.8 mm) to 0.524 mm (CR = 119 mm) and in phase II from 0.601 mm (CR = 149 mm) to 1.024 mm (CR = 362 mm). The thickness increases, then, from the ending of the closure of the secondary interventricular foramen to the end of the fetal period.
