心室

Ventricular pacing may cause interventricular asynchrony but its effect on intraventricular asynchrony need further study.

常规右心室心尖起搏致QRS波增宽，可造成心室间收缩不同步，但不一定会造成左心室内收缩不同步。

The isolated working heart model was set up, high-performance liquid chromatography were used to measure myocardial adenosine triphosphate,total adenine nucleotides, while left ventricular end-diastolic pressure,left ventricular developed pressure, and rate of change of left ventricular pressure were determined before and after preservation.

对照组用St Thomas停搏液停搏并保存大鼠心脏6小时；实验组在St Thomas液中加入前列腺素E1(5 μg/L)停搏并冷保存6小时，利用离体鼠心非循环式Langendorff灌流功能测定模型，测定左心室舒张期末压、左心室发展压和左心室压力变化率，并检测心肌细胞线粒体三磷酸腺苷、腺嘌呤核苷酸总量。

In support of this hypothesis, we show that loss of Tbx5 in the mouse ventricle results in a single chamber lacking distinct identity, indicating a requirement for Tbx5 in septation.

与这一观点相一致的是，Tbx5功能丧失或扩大的小鼠会形成单一心室--既非左心室也非右心室。

Objective To evaluate the effects of pacing in right ventricular septum and right ventricular apex on biventricular synchrony.

目的 评价右心室间隔部起搏和右心室心尖部起搏对双心室同步性的影响。

Methods Men 50 health Chinese people accepted EBCT common transverse and short axis enhanced movie scan(27 men, 23 women, average age 47.7 years.).

方法50例健康人（男27例，女23例，平均年龄47.7岁），利用EBCT横断和心脏短轴电影扫描，分别测量主动脉、肺动脉、左心房和左心室径线，以及左心室心肌厚度、心肌增厚率等；利用心功能分析软件，计算左、右心室各功能指标。

Left ventricular function can be assessed by contrast ventriculography, radionuclide ventriculography, or echocardiography.

通过对比心室造影、同位素心室造影或超声心动图可以评价左心室。

Methods: Randomly divided 80 cases with chronic cardia failure into two groups, regular therapy group and bisoprolol group with 40 cases per group. Regular anticardiac failure therapy, including cardiac and diuretic therapy, was employed to patients in regular therapy group; while the combined therapy of regular therapy and bisoprolol was employed to patients in bisoprolol group. Compared the heart rate, left ventricular diastolic dimension, left ventricular systole dimension, left ventricular ejection fraction before and after therapy and efficiency of both groups.

80例慢性心力衰竭患者随机分为两组，常规治疗组40例，采用强心、利尿等抗心力衰竭常规治疗，富马酸比索洛尔治疗组40例，在常规抗心力衰竭治疗的基础上加用富马酸比索洛尔治疗，对两组临床疗效及治疗前、后心率、左心室舒张末内径、左心室收缩末内径及左心室射血分数的变化进行比较。

Of, relating to, or involving the atria and the ventricles of the heart.

房室的，心房与心室的属于、关于心房、心室的或包含心房、心室的

We characterized left ventricular volume, effective arterial elastance, left ventricular end-systolic elastance, and leftcommunity.

我们应用非侵入性检查手段在社区正常射血分数心力衰竭患者以及对照组中检查具有特征性的左心室容积，有效的动脉弹性回缩率，左心室收缩末期弹性回缩率和左心室舒张期弹性回缩率以及舒张功能等指标）。

The examined subjects were asked to carry out Muller maneuver slowly so that the intrathoracic pressure decreases gradually while the blood flow of the right ventricular outflow tract observed with pulsed Doppler echocardiography at the parasternal short-axis view of the great vessels in the two-dimensional echocardiography.

结果 1。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。模拟胸腔压力变化时，模拟肺血管床和左心室内压力同等程度变化。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.
