心电图

Methods:to analyze electrocardiogram,echocardiogram,left ventriculography,nuclear magnetic resonance results of 13 cases with ahcm.results:12 cases had apical wall thickening in echocardiogram, 3 cases had a "spade-like" configuration on left ventriculogram, 7cases were misdiagnosed as coronary heart disease initially.conclusion:ahcm is easy to be misdiagnosed as coronary heart disease, echocardiogram plays important role in the diagnosis of ahcm, in patients with suspicion of ahcm and inadequate echo images, the use of contrast echocardiography or mri should be considered.

对13例ahcm的心电图、超声心动图、左室造影及磁共振结果进行分析。结果：13例ahcm中心电图有特征性改变12例，超声心动图提示心尖区增厚12例，左室造影提示舒张期呈"黑桃"形改变3例，初诊误诊为冠心病7例。结论：ahcm易被误诊为冠心病，超声心动图是诊断该病的重要手段，必要时可做心脏超声造影术或磁共振检查。

Objective To analyze the clinical and electrocardiogram data of 54 cases of acute aconitine poisoning and to investigate the clinical characteristic and electrocardiogram manifestations.

目的 分析54例急性乌头碱中毒病例的临床和心电图资料，探讨其临床特征和心电图表现。

Results The patients with cardiac amyloidosis had characteristics of large atriums and hypertrophic ventricular walls in echocardiography. And they also had low limb lead voltage in ECG. The ratio of (SV5+RV1) and left ventricle crossing area of all patients were obviously lower than 1.5. Biopsy behaved staining of congo red. And most patients had renal, dermatic and gastrointestinal involvements.

结果 心脏超声心动图表现为患者左、右心房增大，心室肥厚，心腔正常；心电图表现为肢体导联低电压，心电图电压(SV5+RV1)与左心室横截面积CSA比值均明显小于1.5；心外活检表现为刚果红染色阳性，且大部分患者合并肾脏、皮肤及消化系统损害。

Since the most significant difference happened between the middle phase of expiration and the middle phase of inspiration, this result implies that it is the intrapulmonary pressure and the cardiac volume, but not the relative position of the heart and electrodes, which cause the variation of the amplitude of QRS complex.

在一些情况下需要消除呼吸的影响，如高分辨心电图中的波形对齐［1］。这就要求对呼吸影响QRS波形的机制有深入的了解。有些研究通过数学模拟和观察体表电位图，认为呼吸造成心电图变异的主要原因是由心脏与电极的相对位置改变造成的［2，3］，并据此作了一些补偿方案。

Methods: QTc and QTc dispersion in 22 newboms with apnoea and 22 healthy newborns were detected by electrocardiogram mensurative system of Shanghai Huatai Software Engineering Limited Company.

采用上海华泰软件工程有限公司Cardio ExCN100电脑心电图系统12导联同步测定心电图对22例新生儿呼吸暂停患儿的QT间期和QT离散度进行检测，并采用仰卧位和俯卧位两种体位进行测定，并与22例同期正常婴儿进行对照分析。

Methods The dynamic ECG's from 36 orthostatic intolerance pilots and 62 healthy pilots were analysed and compared.

对36名倾斜试验阳性者和62名健康飞行员+Gz作用下的心电图及动态心电图进行对比分析。

I. d. The symptoms of cardio palmus, chest distress, short breath and asthenia and the electrocardiogram, myocardium enzymology and ET,MDA and CRP were observed before and after treatment.

治疗前后观察心悸、胸闷、气短、乏力等证候改变，并检查心电图、动态心电图、心肌酶学及ET、MDA、CRP等指标。

Methods For 286 examples have the determination sickness as if chest stuffily, medical histories and so on palpitation, asthenia make the conventional electrocardiogram to inspect , and does the active flat pack movement experiment and the blood serum calcium examination to 26 examples ST section flat and smooth patient.

我院自2005年1月至5月对286例有自觉症状的患者，做常规12导联同步心电图检查，其结果ST段平展在异常心电图中占有一定的比例，且ST段平展做活动平板运动试验阳性率高达80.77%，值得临床医生高度重视。

对13例ahcm的心电图、超声心动图、左室造影及磁共振结果进行分析。结果：13例ahcm中心电图有特征性改变12例，超声心动图提示心尖区增厚12例，左室造影提示舒张期呈&黑桃&形改变3例，初诊误诊为冠心病7例。结论：ahcm易被误诊为冠心病，超声心动图是诊断该病的重要手段，必要时可做心脏超声造影术或磁共振检查。

The sensitivity, specificity, accuracy, false positive rate were 72.6%(53/73), 31.5%(6/19), 72.6%(53/73), 68.4%(13/19), respectively. The dynamic electrocardiogram false negative rate of a single branch coronary artery was higher than that of multibranch coronary arteries.

动态心电图检出冠心病的敏感性为72.6%(53/73)，特异性为31.5%(6/19)，阳性预测值72.6%(53/73)，阴性预测值33.3%(6/19)，预测准确性为79.3%(73/92)，假阳性率为68.4%(13/19)，假阴性率为27.4%(20/73)；冠状动脉单支病变较多支病变者易出现动态心电图假阴性。

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。
