左心

Therefore, we investigated the effects of levosimendan on the negative inotropic response to ropivacaine in isolated heart preparations of guinea pigs.

因此，我们研究了左西孟旦对于罗哌卡因在离体豚鼠心脏标本产生的负性强心效应的作用。

Background: Left ventricular noncompaction constitutes a primary cardiomyopathy characterized by a severely thickened, 2-layered myocardium, numerous prominent trabeculations, and deep intertrabecular recesses.

背景：左室心肌致密化不全，原发性心肌病的一种类型，以&心肌严重增厚成双层状、异常粗大肌小梁多见、小梁间隐窝深陷&为特征。

Methods: The coronary arterial arterial blood flow, cardiac output, left ventricular pressure, bloodpressure, myocardial oxygen consumption of dogs were recorded by the polygraph system before and after intraduodenal administration of TXL.

测定心肌耗氧量等心脏血流动力学指标。结果：通心络胶囊0.72g／kg剂量组，给药后45min冠状动脉血流量增加了21.56％，同时增加左室作功，与生理盐水组比较有明显差异（P＜0.01）。

Cardiac index and intrapericardial, left ventricular end-diastolic, right atrial, and right ventricular end-diastolic pressures were measured during basal state, after fluid overload, and after pericardiocentesis. Twenty-eight patients (57%) had physical signs of tamponade, and 10 (20%) were hypotensive.

分别于基础状态、容量负荷后和心包穿刺后测量心指数、心包内压、左室舒张末期压、右房压和右室舒张末期压。28例患者（57％）有心包填塞的体征，10例（20％）有低血压。

The time to peak systolic longitudinal strain and the time to peak systolic radial strain were derived from the LV apical views , and to peak systolic circumferential strain was derived from the parasternal short axis. The standard deviation for time to peak longitudinal、circumferential and radial strain in the 18 segments (LS-SD18、CS-SD18、RS-SD18) and the maximal temporal difference of any two segments(LS-dif、CS-dif、RS-dif)were calculated as a strain-derived dyssynchrony index.

方法16例慢性心衰患者，获取心尖长轴观测量各节段收缩期纵向应变达峰时间，径向应变达峰时间，胸骨旁短轴观测环向应变达峰时间，计算CRT术后1个月、术后3个月18节段纵向、环向、径向应变达峰时间标准差(LS-SD18、CS-SD18、RS-SD18)、左室各节段收缩期纵向、环向、径向应变达峰时间最大差值(LS-dif、CS-dif、RS-dif)作为应变非同步指标。

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.

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。

Results Compared with normal myocardium, the peaks of strain and strain rate curve of ischemic myocardium in systole and EF reduced. The postsystolic shortening wave appeared before operation.

结果 术前缺血节段心肌应变和应变率曲线中应变值和收缩期峰应变率值均小于健康人相应心肌节段并可出现收缩后收缩波；术后经治疗的缺血心肌各指标较术前明显增加，PSS波消失，术后左室射血分数有增加。

Results Compared with normal myocardium, the peaks of strain and strain rate curve of ischemic myocardium in systole and EF reduced. The postsystolic shortening wave appeared before operation. Each index increased and PSS wave disappeared after operation.

结果 术前缺血节段心肌应变和应变率曲线中应变值和收缩期峰应变率值均小于健康人相应心肌节段并可出现收缩后收缩波；术后经治疗的缺血心肌各指标较术前明显增加，PSS波消失，术后左室射血分数有增加。

The typical angina is located at the left of the sternum or precordium. The range of pain is fist size, and can radiate to left shoulder and back.

部位 典型的心绞痛位于胸骨区或心前区，有手掌大小范围，可向左肩背部放散。

Intra-utero cardiac intervention therapy was underwent through puncture needle insertion into the left ventricle via the precordium chest wall after anesthesia.

治疗组麻醉后穿刺胎羊心前区胸壁后进入左心室，进行胎羊宫内心脏介入治疗。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
