心电图

Among them, 20 patients were candidates of valve replacement and 18 PDA and pericarditis had their blood samples taken before operation,and 1,2,24 and 48 hours after closure of thorax for measurement of concentrations of CK、CK-MB and TnT,together with ECG recording. Results Of the 60 patients, concentrations of cTnT before operation were normal; 2 hours after aortic unclamping, the correlation coefficient between cTnT and aortic clamping was r = 0.873( P＜0.01), the regression analysis showed Y = 0. 019X-0. 026. Of the 20 patients, ECG showed the myocardium was ischemic; CK、CK-MB and cTnT all rose significantly, reaching the peak after closure of thorax. Of the 18 patients, the ECG and cTnT before operation and after closure of thorax were normal; except 2 patients with pericarditis.

结果 60例瓣膜手术患者术前cTnT均在正常值范围内，主动脉开放后2 h时，阻断时间和cTnT的相关系数为r=0.875(P＜0.01)，回归方程为Y=0.019X-0.026；其中20例瓣膜手术患者心脏经过阻断后，心电图有缺血性改变，周围血液中的CK、CK-MB和cTnT均有明显升高，分别在关胸后2 h达到高峰，数值分别为术前的12.6、9.2和257倍；18例行动脉导管结扎和心包剥脱术的患者术前和关胸后的心电图和血液中的cTnT均正常，CK和CK-MB除2例心包炎患者关胸后出现明显变化外，余均未见改变。

In this thesis, based on the analysis of other electrocardiograph and the character of Digital Signal Processor, a method about the modular design of 12 channels electrocardiograph is described.

本文在分析国内外心电图机和DSP特点的基础上，提出了模块化设计12导心电图机的方法。

Electrocardiograph an ECG uses sound waves to check the rhythm of the heart.

心电图 一心电图利用声波检查的节奏的心脏。

Objective:To compare the diagnosis value among Holter monitoring electrocardiogram,high frequency electrocardiograph and exercise test for coronary artery disease.

目的 比较动态心电图、高频心电图和运动试验在冠心病诊断中的意义。

Electrocardiography is one of the most important non-invasive diagnostic methods, which can be performed at a low cost and allow the early recognition of coronary heart disease.

心电图是临床上检测心血管疾病的一种重要的无创检测方法；近些年来，随着医疗信息化的发展，国内外对于电子心电图的研究已经越来越受到关注。

Results 286 example patient center electrograph exceptionally 203 examples, ST section flat and smooth 26 examples, occupies the unusual electrocardiogram 12.8%, 26 example ST flat and smooth patient moves flat pack movement experiment masculine,21 examples occupies 80.8%.

结果：286例患者中心电图异常者203例，其中ST段平展26例，占异常心电图的12.81%，26例ST平展患者活动平版运动实验阳性21例占80.77%。

In order to verify nicotine effect to heart of rat , analyzing the electrograph Based on these results , it was demonstrated that nicotine can induce to release acetylcholine locally or act on muscarinic cholinoreceptor controlled by parasympathetic nerve .

为进一步确定烟碱对大鼠心脏的作用，对描记烟碱作用后大鼠心电图进行分析，发现烟碱能引起大鼠心电图显示较长的QT间期，增加了PR间期及T波面积，与肾上腺素或去甲肾上腺素引起的QT间期延长相似，且能被M受体阻断剂阿托品所阻断，说明烟碱能够诱导局部释放乙酰胆碱或者作用于部分副交感神经控制的毒蕈碱受体。

However, one major limitation of the standard 12-lead ECG is that it lacks of an integral representation of the time and the amplitude information when depicted on the standard recording chart. Physicians need to visually scan all of the 12 leads for significant abnormalities and then integrate the abnormal features in his mind to learn the location and extent of the cardiac abnormality.

由於十二导程心电图是三度空间的心电讯号投射结果，然而传统的心电图所呈现资讯仅限於时间与振幅的二维变化，缺乏时间与空间整体资讯的呈现；以致於判读诊断上，由於欠缺整体资讯呈现，医师需在脑中进行组合辨识，过程较为繁琐，且对某些病症不易以目视判断。

The cardiogram when be admitted to hospital has room sex period before contractive, the 2d after be admitted to hospital does dynamic cardiogram examination, by room sex rhythm of the heart wrong Lown classifications law [2] . A regards this research as the object with the person that finish order and degree, random cent is two groups, remedial group 30, male 16, female 14, average age 32 years old of; contrast group 30, male 13, female 17, average age is 34 years old.

入院时心电图有室性期前收缩，入院后第2d做动态心电图检查，按室性心律失常的Lown分级法[2]。a以下等级者作为本探究对象，随机分为两组，治疗组30例，男16例，女14例，平均年龄32岁；对照组30例，男13例，女17例，平均年龄34岁。

At the feature extraction stage, the ECG feature points are detected by the moving average method and the differential equation approach.

首先在心电图讯号前处理的部份，利用双向滤波器将杂讯去除，并以移动平均法与微分方程式求得心电图的特徵值。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
