Results In the distal two - thirds of the upper arm, branches of the median nerve constantly formed three fascicular groups. The anterior part of nerve trunk hosted branches to the pronator teres and the flexor carpi radialis. The posterior part of nerve trunk contained the anterior interosseous nerve and branches to the palmaris longus muscle. Branches to the hand and to the flexor digitorum superficialis which was the main trunk of the median nerve at the proximal forearm were grouped to form the middle part.

结果 在臂中、下段，正中神经的分支恒定地组成3个神经束组：旋前圆肌肌支和桡侧腕屈肌肌支束组在神经干的前方，骨间前神经和掌长肌肌支束组在神经干的后方，中间束组是由指浅屈肌肌支和手部分支组成的正中神经前臂主干的近段。

Objective To evaluate the prognosis of different types of bundle branch block during the early acute phase of STelevation myocardial infraction.

目的 评价急性ST段抬高型心肌梗死新发不同类型束支传导阻滞的临床意义。

Quantitative tissue velocity imaging ; Left bundle branch block ; Asynchrony

定量组织速度成像；左束支传导阻滞；非同步性

Methods 20 patients with complete left bundle branch block and 20 normal subjects were studied.

方法对20例完全性左束支传导阻滞患者和20例正常人解剖M型在心室波群区观察室间隔与左室后壁运动；运用频谱多普勒成像技术测量左、右心室射血前期时间（LVPET、RVPET），计算两者之差PETd；采用定量组织速度成像技术测量右室侧壁基底段和左室各壁基底段达收缩期峰值速度时限和达舒张早期峰值速度的时限。

Powerful predictors of a positive test are an ejection fraction le than 40%, bundle branch block, or atrial fibrillation.

对射血分数小于40%及束支传导阻滞或房性纤颤的阳性检查效果最好。

Junction rhythm block in four patients, second-degree heart block in one, and right bundle branch block in four patients.

9例(8%)患者并发其他心律失常：包括4例节律阻滞，1例II度房室传导阻滞，4例右束支传导阻滞。

Despite of the intricate modification in the surgical management of the perimembranous ventricular septal defect, the postoperative prevalence of the complete right bundle branch block had remained high with values ranging from 20 to 62%.

尽管膜周室间隔缺损的手术方法已经过各色各样的改动，但术后完全性右束支传导阻滞的发生率仍高达20%～ 62%。

ECG data of healthy people and three kinds of heart disease patients (premature ventricular contraction, bundle branch block and supraventricular) which are analyzed in this thesis are derived from MIT-BIH ECG database.

本文采用MIT-BIH心电数据库中的健康人和室性失常病人、束支传导阻滞病人、室上病变病人等3种类型心脏病人的数据作为样本进行分析。

VT and PVC originating from RVOT had the typical ECG characteristic which showed left bundle branch block with an inferior axis.

RVOT起源的VT和PVC具有典型的心电图特征，表现为典型的左束支传导阻滞型伴电轴右偏。

The incidence of major abnormal ECG were 7.3% for STT changes, 5.6% for sinus tachycardia, 4.4% for sinus arrhythmia, 3.4% for ventricular premature beats, 2.0% for bundle branch block and 1.8% for atrial premature beats; Apart from preexcitation syndrome, the incidence of abnormal ECG for male was higher than that of female;Most of abnormal ECG increased with age. A few abnormal ECG such as sinus tachycardia, sinus arrhythmia, sick sinus syndrome decreased with age. The incidence of sinus bradycardia and preexcitation syndrome were bail shape with age. Half of abnormal ECG adults had at least two abnormal ECG, such as STT changes combined with ventricular premature beats or bundle branch block.

异常心电图较多的有STT改变（7.3%）、窦性心动过速（5.6%）、窦性心律不齐（4.4%）、室性早搏（3.4%）、束支传导阻滞（2.0%）、房性早搏（1.8%）；除预激综合征外，其他异常心电图都是男性多于女性；多数异常心电图的检出率随年龄增加而增加，但窦性心动过速、窦性心律不齐、病窦综合征随年龄增加而减少，窦性心动过缓和预激综合征的检出率与年龄呈&杓形&关系；在异常心电图人群中，有约1/2的人合并2种或2种以上的心电图改变，最常见的是缺血性STT改变合并室性早搏或传导阻滞。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
