| 1. | Regurgitant murmurs are generally early diastolic whereas ventricular filling murmurs occur in mid and late diastole 回流性杂音一般出现于舒张早期,而心室充盈性杂音一般出现于舒张中晚期。 |
| 2. | An alternative classification emphasizes etiology : regurgitant murmurs from semilunar insufficiency versus ventricular filling murmurs 另一种分类则着重于其病因:由半月瓣闭锁不全所致的回流性杂音对心室充盈性杂音。 |

| 4. | 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 |
| 5. | Simulated experiments effects of intrathoracic pressure change on hemodynamics model i and ii tests demonstrated that the same itpc had different actions on the simulated ventricular fillings . the itpc would not change the pressure in the simulated right heart but its volume while it changed the pressure in the simulated left heart without direct influencing on its volume 模拟实验胸压变化对血流动力学的影响3第四军医大学博士学位答辩论文外周静脉压和模拟胸腔压力变化相同时所引起的右心室容积的变化是相同的;当两者同时同步变化时,右心室容积无变化。 |
| 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。 |
