心耳

Some electrophysiological index were measured, including atrial effective refractory period, rate adaptability, dispersion of AERP, inducibility and duration of induced atrial fibrillation under different basic pacing cycle length (300, 250 and 200 ms). Results: Contrast with control group, the values of AERP at 6 sites were shortened and maladaptation.

Analyzing the characteristics of Bach's work, combining with application and general using law of pedal, the paper presents the reasons of debate and puts forward some suggestions: connecting two tunes, retouching psalterium tune and resonating chord need pedal when playing Bach's piano works; auditory is the key to decide whether to use pedal or not; using pedal should consider arrangement of harmony in Bach's polyphonic works.

依据巴赫作品的特点，结合踏板的使用与一般运用规律，弹奏巴赫的钢琴作品时，在连接两音、润色琴音及和弦共鸣时是需要使用踏板的，听觉是决定是否使用踏板的关键，使用踏板应特别考虑到巴赫复调作品中和声的安排与进行，即应做到"心耳相随，有机结合"。

Puncture into Attain long sheath of CS through left infraclavicular vein, guided by CS pipe, take sheath into CS, make reverse contrast of heart vein with Attain saccule contrast pipe, put the left ventricle electric pole into the vein through sheath, then bring it into right ventricle apex and right cardiac ear through the electric pole of right ventricle and atrium, connect it with 3-cavity pulse generator, which is buried under left chest skin.

These data suggest that fibrosis exist in the atrium of a hypertensive rat model induced by suprarenal abdominal aorta banded.

1.3 标本的采集及处理打开已测定好血压大鼠的胸腔，分离心脏，切取左、右心耳并用10%中性甲醛固定。

Results Three different flow wave pattern were observed,consisting of quadriphasic pattern,triphasic pattern and biphasic pattern.

结果 窦性心律左心耳血流频谱的波相可分为4相、3相、2相三类。

Objective To provide anatomical basis of positioning pacing electrodes by measuring right auricular wall thickness and interpectinate foveae depth.

目的 通过测量右心耳壁厚度及梳状肌间凹深度，为临床心房起搏电极的定位提供解剖学基础。

The heart is a hollow, muscular organ that weighs about 342 grams and beats over 100 000 times a day to pump 3 784 liters of blood per day through over 60 000miles of blood vessels.

2， 心脏内部有4个接受循环血液的腔。上方有两个腔为左心房和右心房。每个心房有一个附器，因其形状酷似狗的耳朵而被称为心耳。

The P wave duration and P 2R interval were increased while pacing at right atrial appendage 1 The activation time from pacing site to His bundle and coronary sinus was the longest in pacing at right atrial appendage , while the activation time in pacing at Koch triangle , Koch triangle with high right atrium and biatria was significantly shorter especially pacing at Koch triangle and Koch triangle with high right atrium1 There were no significant differences in right atrium pressure among all pacings1 Conclusion It is suggested that Koch triangle pacing could probably replace high right atrial with coronary sinus pacing and biatrial pacing 1

从心房激动顺序分析，右心耳起搏时，激动传至希氏束区及冠状窦区的时间最长，而 Koch三角、Koch三角+高位右房及双房起搏时则较短，尤其是 Koch三角、Koch三角+高位右房起搏缩短更明显。另外，不同部位、不同方式起搏时右心房压力无差异。结论 Koch三角起搏在某种程度上可替代高位右房+冠状窦起搏及双房起搏。

The 4th left rib was cut and a model of left coronary artery occlusion/release was carried outo Rats were divided randomly into 4 groups: control group without LCA occlusion (group A, n=6);I/R group(group B, n=6); ketamine(5mg.kg-1)+I/R group (group C, n=6); ketamine(10mg.kg-1)+I/R group(group D,n=6)o All rats in groups B, C , D were subjected to 30 minutes of LCA occlusion followed by 120minutes of reperfusion. Rats in group C and D were injected with 5mg.kg-1 and 10mg.kg-1 of ketamine before reperfusion, respectively. Significant electrocardiogram and color changes at the area at risk were considered indicative of successful coronary occlusion and reperfusionc Serum was exampled from left jugular vein at 30 minutes and 120 minutes during reperfusion to measure IL-6 and TNF- level by ELISA measurements. After reperfusion of 120 minutes, the heart was removed and the cardiac apex was exampled with snap-frozen in liquid nitrogen and stored at -70 C .
