查询词典 heart contraction

Primary atrial tumor has obvious characteristic on RT-3DE: All the atrial tumor display the same size of stereoimages as the tumor themselves. There is a clear boundary between the stereoimage of the myxoma and the atrial wall and there exists a short pedicle connecting the atrial myxoma to the atrial wall or the interatrial septum. The body of the atrial myxoma moves to and fro through the atrium and the atrioventricular valve with the contraction and relaxation of the heart with a fixative pedicle. Atrial myxoma leads to relative atrioventricular valve incompetence during systolic phase and relative atrioventricular valve stenosis during diastolic phase, but doesn't result in pathological changes of atrioventricular valve which restore to normal after exsection of the atrial myxoma. Malignant atrial tumor closely and extensively contact with atrial wall without obvious boundary, pedicle and movement with the contraction and relaxation of the heart.

所有心房肿瘤RT-3DE均实时显示与肿瘤大小相同的立体形态图像；心房黏液瘤立体形态图像与心房壁界限明显，都通过一短蒂与房间隔或心房壁相连，瘤体以蒂为固定点随心脏收缩、舒张在心房与房室瓣口之间往返运动；心房黏液瘤收缩期瘤体导致房室瓣相对关闭不全，舒张期瘤体导致房室瓣相对狭窄，但瘤体不引起房室瓣器质性病变，瘤体摘除后房室瓣功能即恢复正常；恶性心房肺瘤立体形态图像与心房壁关系密切，界限不明显，接触范围广泛，无蒂，瘤体不随心脏收缩、舒张运动。

In the first 2-3 hours there is always a strengthening of contraction, while after 5-10 hours, when the heart gives much feebler contraction due to exhaustion, this beneficial effect of phosphatide tends to disappear.

二葡萄糖在灌流液中的作用视室温与离体时间而定。在较高室温长期灌流而衰竭的心脏，葡萄糖是必要的，它可以维持心肌收缩并被心肌所消耗。如心脏离体时间较短，室温较低，则葡萄糖并非必需。

Pressure, which reflects the higher systolic blood pressure and heart contraction strength is higher,...

压力大，则反映收缩压较高和心脏收缩强度较高，。。。

The main problem of most patients suffering from heart failure is the decreased force of cardiac contraction. Meanwhile, the heart inotropic, chronotropic and dromotropic effect is in a state of intricacy and constant flux due to a variety of patients' condition or treatment.

大多数心力衰竭病人的主要问题是心肌收缩力的降低，与此同时，心脏变力性、变时性和变传导性也因病情的不同或者治疗的不同而处于一种复杂的、不断变化的状态。

MPG has the actions of enhancing myocardial contraction, improving myocardial compliancy and left ventricular systolic and diostolic function and increasing cardiac output and arterial blood pressure in heart failure cats caused by Pentobarbital sodium.These show MPG is beneficial to releasing heart failure.

甲基葡萄糖苷对戊巴比妥钠诱发的实验性心衰猫具有加强心肌收缩力、改善心肌顺应性和左室舒缩功能、增加心排血量、升高动脉血压的作用。

In a normal heart rhythm, the impulse generated by the sinoatrial node spreads through the heart and causes contraction of the heart muscle and pumping of blood.

在正常的心律时，由窦房结产生的脉冲传播通过心脏，并导致心肌收缩和泵送血液。

Finally statistical analysis is conducted.Result: Orally taking Xuefu Zhuyu Tang and calming-wind medicines can ease stenocardia,improve ECG,enhance the stopped rate of nitroglycerin,better the heart contraction and dilation,regulate blood fat,promote blood rheology,lower CRP、ET、TXB2,raise NO、6-keto-PGF1αand so on,compired with the control group,it is obviously statically meaningful without obvius adverse reaction.

结果：血府逐瘀汤加治风活络药物内服治疗能有效地缓解心绞痛和临床症状；改善心电图；提高速效扩冠药的停减率；改善心脏的收缩及舒张功能；调节血脂；改善血液流变学；降低CRP、ET、TXB2的水平，升高NO、6-keto-PGF1α的水平等，与对照组相比，有显著的统计学意义，且未发现明显的不良反应。

The paired peptidergic buccal ganglion neurons RB 1 and LB 1 have dramatic modulatory effects on both the feeding motor program and the force of heart contraction (Wels- ford and Prior, 199 1). The B 1 neurons appear to contain the small cardioactive peptides.

配对肽能口神经节中的神经元RB1及LB1对摄食动力神经程序和的心脏收缩力都有很强的调节效果。B1神经元中有少量作用于心脏的缩氨酸出现。

The spiracles are bigger and more near dorsal line than all the others. Their trachea branches are taper and abundant and form short tracheoles. This gave the tufted form to the trachea, which appeared shrubby. The trachea branches that arranged in other segments gave them a tree-like look. They do not directly supply oxygen for tissues, but they suspend in the hemolymph and attach to the muscle of the heart, so that they can move in constant with the contraction of the heart muscle.②The 8th segment tracheal tufts have thinner cuticle and basal lamina than that of the other trachea, and have much pad cuticle, which is appropriate for them to move, and their basal lamina have small pores, which are favour of the permeation of gas.③Injecting the methylene blue into the larvae to label hemolymph, we observed that the hemolymph flow into the heart through the 8th segment tracheal tufts.④Normally these tracheal tufts have all kinds of hemocytes, which are abundant in the tufts. A large number of hemocytes released from tissues attach to the tufts by changing their structure when anoxic stress happen.

气管分支细短而丰富，形成气管簇，呈灌木丛状（其它各节气管则呈粗树干状分布），它不是直接给组织供氧，而是悬浮在血液中，与心肌相连接，随着心肌的收缩而不断运动；②气管簇的内膜及底膜都比其它各节的薄，且管壁内膜具有更多的适合运动的垫状表皮，底膜还有小孔结构，这有利于气体的通透；③向体内注射蓝色的亚甲基蓝标记血液发现，血液流动方向是经该气管簇后而流回心脏；④正常情况下，气管簇处有各种各样的血细胞聚集，当缺氧胁迫时有大量的血细胞从组织中释放出来，通过变形而紧贴气管簇，有利于气体的交换；⑤给体内注射无色的亚甲基蓝发现气管簇比其它各节更易变蓝，说明该处具有更高的获氧能力。

Late decelerations are characterized by a smooth U-shaped fallin the fetal heart rate beginning after the contraction has startedand ending after the contraction has ended.

晚期减速的特点是胎心率有一个平滑的U型减速，在宫缩已经开始以后出现，在宫缩高峰过后结束。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
