| 1. | The interventricular septum of the heart has been sectioned to reveal an extensive acute myocardial infarction . the dead muscle is tan - yellow with a surrounding hyperemic border 心脏室间隔的断面显示了广泛的急性心肌梗死。坏死心肌呈棕黄色,与周围充血心肌分界清楚。 |
| 2. | Figure 4 - 34 . embryology of the atrioventricular junction . the primitive atrioventricular canal is partitioned by the growth of the endocardial cushions ( ec ) , interatrial septum ( ias ) , and interventricular septum ( ivs ) 房室交界处的胚胎发育。原始房室管生长分化为心内膜垫( ec ) ,房间隔( ias )和室间隔( ivs ) 。 |
| 3. | Objective l . to investigate the mechanism of the different influence of the intrathoracic pressure change ( itpc ) on the two ventricular fillings and the motion of interventricular septum 目的1建立模拟实验模型,观察胸压变化对左、右心充盈及室间隔运动的影响,从力学角度验证我们提出的呼吸影响心功能机制新假说; 2 |
| 4. | To observe influence of respiration on hemodynamics and interventricular septal ( ivs ) motion in patients with pericardial effusion ( pe ) with echocardiography and to provide theoretical basis for its clinical application 观察心包积液患者胸压变化时心内各瓣口血流速度变化及室间隔运动情况,为临床无创定量心包填塞严重程度提供依据; 4 |
| 5. | Results : there are 20 cases of fchd , in which 2 cases is of endocardial cushion defect , 3 of atrial septa defect , 2 of single atrium , 2 of single ventricle , 2 of double outlet of right ventricle , 2 of ebstein ' s malformation , 5 of interventricular septal defect , 2 of fallot ' s tetrad . 16 cases were diagnosed by ultrasonography and 4 cases were missed diagnosis in prenatal 结果:发现20例胎儿有先天性心脏缺陷,其中完全性心内膜垫缺损2例,原发孔性房间隔缺损3例,单心房、单心室、右室双出口、三尖瓣下移畸形各2例,室间隔缺损5例,法乐四联症2例。 |
| 6. | Simulated experiments effects of intrathoracic pressure change on hemodynamics three models that simulated the anatomic arrangement of the venous return systems and chest cavity were established to investigate the hydromechanic principle of the different influence of the itpc on the ventricular fillings . effects of intrathoracic pressure change on the motion of interventricular septum ( ivs ) acuson ' s sequoia 512 ultrasonographic system was used in this study to record the m - mode and two - dimensional cineloop images of the simulated interventricular septum movement with different intrathoracic pressure changes 指标观测观察并记录外周静脉压和模拟胸腔压力分别变化及同时变化时,模拟右心室的容积变化;观察并记录模拟胸腔压力变化时,模拟肺血管床和左心室内压力的变化;用sequoia512超声心动图仪观察胸腔压力变化对模拟心脏室间隔运动的影响。 |
