心脏舒张的

Cardiac output by the diastolic venous return by blood to the heart and the effects of cardiac contractility.

心输出量受心脏舒张时由静脉回流到心脏的血液量和心脏收缩力的影响。

FMD of the brachial artery was examined by high-resolution ultrasonography technique and the inter-ventricular septum thickness, left ventricular posterior wall thicknessand left ventricular diastolic diameter were measured by echo-cardiography technique. The left ventricular mass and LVMI were calculated according to Devereux formulary. According to Framingham heart study, The hypertensive individuals were separated into two groups, left ventricular hypertrophy group and without left ventricular hypertrophy group.

利用高分辨超声技术测定肱动脉血流介导的舒张功能；超声心动图评价受试者的心脏结构功能，测量室间隔厚度(inter-ventricular septum thickness， IVST)、左室后壁厚度(left ventricular posterior wall thickness， LVPWT)及左室舒张末内径(left ventricular diastolic diameter， LVDD)，根据Devereux公式计算(left ventricular mass， LVM)按体表面积得出LVMI，并据Framingham心脏研究的标准将高血压组分为左室肥厚组(24例)与无左室肥厚组(31例)。

An increasing content of elastin is typical of larger arteries that need to provide for considerable elastic recoil during diastole, the time period between ejections of blood from the heart.

典型的大动脉必须在血液从心脏流出的舒张期间提供相当大的弹性回缩，所以需要有愈来愈多的弹力蛋白。

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。

These substances are strong vasodilator agent, can reduce peripheral vascular resistance and coronary heart against the human body catecholamine pressor substances, such as the role, but also to promote the excretion of sodium, so that blood pressure dropped.

这些物质均为较强的血管舒张剂，能减少外周血管和心脏冠状动脉的阻力，对抗人体内儿茶酚胺等升压物质的作用，又能促进钠盐的排泄，从而使血压下降。

Methods:Paticipants consisted of 32 simple VSD patients and 27 simple PDA patients excluded of any other diseases by physical examintation and electrocardiogram and x-ray. Patients were suggested echocardiography before and one week after the surgerys. Parameters such as Left ventricular ejection fraction、Fractional shortening、Left ventricular end-diastolic dimension、Left ventricular end-systolic dimension、Heart rate and Aortal velocity peak were measured.further more ,the Tei index which is originated from Pulse-wave Doppler and Tissue-Doppler Imaging were also calculated under ECG monitoring.

研究对象与方法：研究对象分别为排除其它心脏疾患的单纯动脉导管未闭患儿及单纯室间隔缺损患儿，手术治疗前后于心电监护下先行常规超声检查，获取心率、R-R间期、左室射血分数、主动脉峰值流速、左室收缩末期内径及左室舒张末期内径等值，并分别利用频谱多谱勒及组织多谱勒法测取患儿左室Tei指数(即PW-Tei及TDI-Tei)，多次测量并取其均值。

The restrictive filling pattern seen with severe heart failure may be due to diastolic dysfunction with elevated left ventricular diastolic pressure or may be merely a manifestation of an overfilled LV as a result of increased left atrial pressure.

限制性充盈模式被看作为严重的心力衰竭，其可能是由于增高的左室舒张压导致心脏舒张功能障碍或者可能仅仅是由于增加的左房压引起左室过度充盈的一种现象。

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。

Normally the heart movements can be felt as distinct systolic and diastolic thumps.

正常时，能够感觉到心脏的运动是性质截然不同的收缩和舒张的撞击。

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。
