The aortic nerve stimulation produced depressor and bradycardic responses were elicited in urethan and chloralose aneasthetized rabbits.

电刺激家兔一侧主动脉神经引起心动过缓和降压反应。在同侧孤束核内注射γ氨基丁酸或吗啡，能基本阻断这种诱发的心动过缓和降压反应，但不影响基础血压和基础心率。

The accuracy, sensitivity and specificity of the prediction to the myocardial viability were evaluated with DSE according to the actual recovery of the myocardial contractibility about six months after PCI.

以冠脉介入治疗术后6个月静息超声心动图心肌收缩运动恢复情况为标准评价多巴酚丁胺负荷超声心动图预测存活心肌的准确性、敏感性和特异性。

The left ventricular internal dimension at end diastole, interventricular septal thickness at end diastole and left ventricular posterior wall thickness at end diastole were measured in the parastemal long axis view by transthoracic two-dimensional echocardiography, and to calculate left ventricular ejection fraction with Teichholtz formula and left ventricular mass with modified Devereux formula, left ventricular mass index=LVM/body surface area. From the apical four chamber and two chamber view, the basical segment and middle segment of interventricular septal, left ventricular lateral wall, anterior wall and inferior wall were obtained by tissue Doppler imaging, Regional left ventricular relaxation asynchrony index was calculated.

应用二维超声心动图在胸骨旁左心室长轴观测量左心室舒张末期内径、室间隔和左心室后壁舒张末期厚度，采用Teichholtz公式计算左心室射血分数，采用Devereux校正公式计算左心室心肌质量，左心室心肌质量指数=左心室心肌质量/体表面积；在心尖四腔心和心尖两腔心切面，应用组织多普勒成像获取室间隔、左心室侧壁、前壁和下壁的基底段和中间段8个心肌节段沿左心室长轴运动的速度频谱，测算左心室局部心肌松弛不同步性指数(regional left ventricular relaxation asynchrony index， AI)；在心尖四腔心切面，应用彩色M型多普勒超声心动图测量左心室舒张早期血流传播速度。

The cardiac cycle includes two phases:systole and diastole ,which forms into one mechanical activity cycle.

心动周期：心脏一次收缩和舒张构成一个机械活动周期，称为心动周期。

Methods 14 cases of sudden cardiac death or cardiac syncope by malignant rapid ventricular arrhythmia of long interval dependent ventricular extrasystole, including 8 TdP cases 、5 VF cases and 1 VT case were treated by temporary cardiac pacing.

长间歇依赖室性早搏诱发的恶性快速性室性心律失常所导致的心源性晕厥或猝死患者共14例，包括尖端扭转型室性心动过速 8例，室颤5例（2例由TdP转化而来），持续性单形性室性心动过速1例，呈反复发作的特点，予临时心脏起搏治疗。

Junctional ectopic tachycardia and/or ventricular tachycardia may be characteristic of an acute stage of heart block.

交界性异位心动过速和/或室性心动过速可能是心脏传导阻滞急性期的特征。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
