According to the echocardiography,enlarged internal diameter of left ventricle was found in 8 patients and short-axis fractional shortening of left ventricle 5% in 3 patients.Six out of the above 8 patients presented with shortening of accerlerating time,decreasing of accerlerating time/right ventricular ejective time value and moving forward of spectral peak in different degrees.All patients were given antianginal drugs such as β-recepter blockers,nitrate preparations and part by angiotensin converting enzyme inhibitor,diuretics and digoxin,The illncss of 29 patients were gradually controlled within one week.Three patients with AD were complicated by acute left heart failure.No obvious changes in FS of left ventricle were found on echocardiography by bed.

测量肺动脉瓣口血流频谱，左心室内径增大的8例中有6例出现不同程度的血流加速时间缩短，血流加速时间/右心室射血时间比值减小，频谱峰值前移。31例均给予β受体阻滞剂、硝酸酯类等抗心绞痛治疗，部分给予血管紧张素转换酶抑制剂、利尿剂和地高辛，其中29例在1周内卧位型心绞痛逐步得到控制。3例卧位型心绞痛发作时合并急性左心衰竭者，在床旁观察超声心动图，发现左心室短轴缩短率无显著变化，给予利尿剂、减轻前后负荷等治疗，急性左心衰竭得以纠正。

The myocardial M cells lie mainly between endocardium and epdocardiumabout 30-40 of all myocardial cells.

心肌 M 细胞主要位于心室内膜细胞和心室外膜细胞之间，约占心室总体细胞的30－40%。

Objective:To investigate the interventricular and intraventricular synchronization in subjects with dual chamber pacemaker by tissue doppler imaging.

目的：分析永久性起搏器植入术后右心室起搏患者的心室间及心室内非同步收缩的特点及影响因素。

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: 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。

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）。

Results: Cords could be found both in the left and right ventricles. The frequency of the ventricular cords in the left and right ventricles was respectively 88.89% and 85.19%. The false tendon were classified into four types: muscular, conductive, mixing and tendinous. The muscular cords were composed of cardiomyocytes. The conductive cords contained Purkinje cells, T cells and a few P cells. The mixing cords consisted of cardiomyocytes and a few P cells.

结果：左、右心室均存在心室条索，出现率分别为88.89%和85.19%；心室条索分为肌型、传导型、混合型和腱型4种类型，肌型由普通心肌细胞构成；传导型含有Purkinje细胞、移行细胞和少量的P细胞；混合型含心肌细胞和少量P细胞；腱型由结缔组织构成。

Walter Abhayaratna, M.D., senior lecturer, Australian National University, said LV untwisting velocity is a sensitive marker of LV function.

据澳大利亚国立大学高级讲师Walter Abhayaratna医师所述，心室解旋速率是用于测量左心室收缩和松弛期间的心脏扭转运动，是反映左心室功能的一项敏感指标。

The results showed that the rates of confirmation between the onsets of acceleration around ventricular wall and the positions of electrode of esophageal pacemaker or RV pacemaker both were 100% during stimulation.

结果发现：心室壁加速度改变起始点位置与食道调搏和心室起搏电极位置的吻合率在左右心室分别均为100%。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
