心脏收缩的

The human heart is the center of the cardiovascular system. Integrated with mechanical, electrical, neural and biochemical properties, the heart is difficult to model, and there is no ideal integral model now. The developed electrical models haven't considered the mechanical properties and blood flow process in the heart; while the mechanical ones have normally deal with the heart in the diastole period, and the electrical activity was simplified too much although some mechanical models have investigated the heart during systole.

心脏是循环系统的核心，它集机、电、神经和生化控制于一体，建模难度很大，目前尚无较理想的统一模型；心脏电生理模型未与心脏的机械动力过程和血液流动过程联系起来；而心脏力学模型大都只研究舒张期的力学特性，即使研究收缩期心脏的力学问题，也往往对心电兴奋做了许多简化假设。

These relative risks did not change significantly after adjustment for age; sex; total cholesterol, low-density lipoprotein cholesterol, or triglyceride levels; carotid-wall thickness; smoking status; the presence or absence of diabetes and systolic and diastolic hypertension; body mass index; and other risk factors. In women, Lp lipoprotein levels were not related to cardiovascular risk, even after adjustment for estrogen use or nonuse.

这些相对危险性经过年龄、性别、总胆固醇、低密度脂蛋白胆固醇、或三酸甘油酯浓度、颈动脉管壁厚度、吸烟状态、糖尿病和心脏收缩及舒张高血压的有无、身体质量指数、和其他的危险因子的调整后并没有显著改变，而在女性方面，Lp脂蛋白浓度与心血管风险无关，即使经过雌激素有无使用的调整后也是如此。

The contraction of the chambers of the heart to drive blood into the aorta and pulmonary artery .

心脏各室的收缩，收缩时把血液压入大动脉和肺动脉。

For many years it was believed that reduced myocardial contractility or systole dysfuction was the sole distrubance in cardiac fuction responsible for heart failure.

多年来，据认为，降低心肌收缩力和收缩功能障碍是心脏作用分析唯一的震荡心力衰竭负责。

A strain analysis approach of the left ventricle is proposed.

提出一种直观地分析左心室在心脏收缩期的应变情况的方法。

Dobutamine stress echocardiography, radionuclide ventriculography, and right heart catheterization in the BMC group also showed significant improvement in stroke volume index, left ventricular end-systolic volume and contractility (ratio of systolic pressure and end-systolic volume), and myocardial perfusion of the infarcted region.

Dobutamine压力心脏超音波检查，放射性核脑室造影术和右心导管插入都显示，BMC组的脉搏容积指数、左心室终末收缩容积和伸缩力（收缩压和终末收缩容积比）以及梗塞区域心肌灌注明显改善。

Results: Hedgchlum Coronagium Kocnlg is poisonless and edible, containing a great deal of nutrition, especially proteins such as, Fe, Zn, Ca. It has more essential amino acid than any other flowers and plants. High thickness of Hedgchlum Coronagium Kocnlg juice can improve the mice's heart-rate and enhance the contractility of rats' heart which have been cut from their bodies.

结果：实验证实白姜花无毒可食用；含有各种营养物质，特别是蛋白质、铁、锌、钙含量较高；人体必需氨基酸含量也居其它花卉之首；高浓度原液有提高小白鼠的耐力、减慢大白鼠心率以及增强大白鼠离体心脏收缩力的作用。

Inhibition of 〓 exchange decreases the systolic and diastolic function of perfused hearts, whereas stimulating 〓 exchange improves the cardiac function, indicating that potentiating 〓 exchange may be a new pathway to improve the pump function of heart.

抑制〓交换可降低正常大鼠心脏的收缩和舒张功能，激动〓交换可增强正常大鼠心脏的收缩和舒张功能，提示增强〓交换可能是提高心泵功能的一个新途径。

A hormone secreted by the posterior lobe of the pituitary gland that constricts blood vessels, raises blood pressure, and reduces excretion of urine.

用来治疗高血压和心律不齐的药物；通过阻止神经系统肾上腺接受器来减少心脏收缩力的药物。

Elevated systolic blood pressure of the impact on cardiac function may be greater than the diastolic blood pressure.

收缩压的升高对心脏功能的影响可能大于舒张压。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
