Through the multiple stepwise regression analysis, the duration of the disease and serum GH level were the main influencing factors of acromegalic cardiomyopathy. 2 Ejection fraction and fractional shortening, were decreased, compared to control group, they still remained in normal range. 3 Isovolumic relaxation time and E wave descending time, were delayed apparently compared to control group, indicating the damage of cardiac relaxation. 4 Subgroup analysis in acromegalic: The comparison between patients with diabetes mellitus and impaired glucose tolerance and patients without DM/IGT showed that there was no significant difference in terms of the parameters in the two groups, in spite of an mild increase of IVST in the former group.

经多元逐步回归分析，病程和血清生长激素浓度为心肌肥厚的主要影响因素。2实验组射血分数和左心室短轴缩短率虽较对照组低，但仍在正常范围。3实验组左心室等容舒张时间和二尖瓣减速时间较对照组明显延长。4实验组中继发糖尿病／糖耐量减低组与非DM/IGT组进行比较，前者仅室间隔有较明显增厚，其余各项参数2组间差异均无统计学意义。

Results: The left and right ventricular pressure curves of each cardiac cycle from the analogue experiment are much close to the pressure curve in human physiological system.

结果 ：模拟实验得到的左、右心室心动周期压力曲线和正常生理情况下的左、右心室心动周期压力曲线非常接近。

The present invention shrinks the tissue in the heart (10) by selectively heating infarcted scar in order to reduce the size of the surface of the infarcted scar, make the soft part of the scar tissue become rigid, reduce the wall tension of shrinking the ventricle, and increase the total pump efficiency of the infarcted heart (10) by removing ventricle aneurism.

本发明通过有选择地加热梗塞瘢痕，收缩心脏（10）中的组织以缩小瘢痕组织表面积（18）的大小、使瘢痕组织的松软部分变硬、减少心室收缩的壁张力，并通过消除心室动脉瘤来增加梗塞心脏（10）总泵送效率。

Observational studies suggest that conventional right ventricular apical pacing may have a deleterious effect on left ventricular function.

观察研究表明传统的右心室心尖起搏可能对左心室功能有害。

Obserdose of noradrenaline bitartrate or KCl: Sub-maximal constriction of thoracic aorta was induced by 0.1 mmol/L noradrenaline bitartrate or W60 mmol/L KCl, and when constriction curve became stable, DL or nimodipine of different dosage was added.

记录电刺激心室乳头肌时收缩的幅度变化：1次/s，波宽3 ms，阈电压的120％强度电刺激以引发心室乳头肌同步收缩活动，待收缩曲线平稳后，分别用累加法加入二氢石蒜碱或尼莫地平。

objective trimetazidine has shown anti-ischemic properties to improve exercise tolerance without haemodynamic effects and direct cyto protective effect on the myocardium.however,it is not clear whether trimetazidine has beneficially effect on severe ischemic cardiomyopathy.methods 19patients（68±9）years with postnecrotic left ventricular dysfunction（ejection fraction31.7%±5.4%）were studied to examine the benefit of adding60mg a day of trimetazidine for3months to the classical therapy.the assessment included clinical evaluation,electrocardiography and echocardiography.results after adding60mg a day of trimetazidine for3months,attack of angina was relieved and dyspnea was improved（p.05）.but heart rate,systolic blood pressure,rate pressure product,ejection fraction,left ventricular volume and global wall motion index were not changed.conclusion trimetazidine seems to improve clinical status while can not change oxygen supply-to-demand ratio without adverse effects in patients on severe ischemic carˉdiomyopathy.

目的 曲美他嗪是一种新型的抗心肌缺血的药物，能够改善患者的运动耐量和心肌的直接保护作用同时并没有血流动力学效应。但目前对于严重缺血性心肌病患者的临床治疗价值还需要进一步观察。方法 19例（68±9）岁确诊为缺血性心肌病（左心室射血分数0%）的患者在常规治疗的基础上加用每日60mg曲美他嗪治疗3个月，随诊观察患者临床情况以及超声心动图指标的变化。结果 19例患者均可耐受在常规治疗基础上加用每日60mg曲美他嗪的治疗，随诊发现患者心绞痛发作明显减少，运动耐量明显改善。同时患者心率、收缩压、心率血压乘积、左心室射血分数、左心室容量以及整体室壁运动指数无明显改变。结论缺血性心肌病的患者在常规治疗基础上加用曲美他嗪是安全的，同时其能明显改善患者的临床状态，而这种作用并不改变心肌氧的供求比值。

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。

Two of these pump blood to the lungs, where it picks up oxygen, then the other two pump this oxygenated blood throughout the body. One of these four chambers—the left ventricle—contracts most strongly to pressurise the blood.

相比之下，人的心脏只有四个心室，其中的两个心室收缩将血液压进动脉输送到肺部，在那里吸收氧气，放出二氧化碳，而另两个心室则将完成气体交换后的血液输送到到全身。

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%。

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。
