心电图

Objective:To analysis the electrocardiogram in 40 patients with dilated cardiomyopathy.

目的：分析扩张型心肌病的心电图改变，为临床诊断治疗提供依据。

Calculate Lyapunov spectrum of series of R-R intervals and R-wave peaks with different physiological and pathological states. On the basis of Lyapunov spectrum, first propose the concept of Rate of Convergency-Divergency which can judge dynamics characters of the heart by both convergency and divergency.

计算了不同生理病理状态下动态心电图中RR间期和R波峰序列的Lyapunov指数谱，并以此为基础首次提出了收敛发散比的概念，它可以从收敛和发散两个方面衡量心脏系统的动力学特征。

The n make a conbrast analysis to the time domain and frequency domain of heart rate variability.

对86例海洛因依赖患者与89例对照组进行全程24 h动态心电图检查，并行心率变异性时域和频域分析对比。

Methods Make a 24-hour dynamic ECG to 86 drug addicts and 89 normal subjects.Then make a conbrast analysis to the time domain and frequency domain of heart rate variability.

对86例海洛因依赖患者与89例对照组进行全程24 h动态心电图检查，并行心率变异性时域和频域分析对比。

The physical examination was normal except for hypertension and absence of left-side dorsalis pedis artery pulse. Electrocardiography and cardiac enzyme levels were both normal.

理学检查发现高血压及左侧足背动脉的脉动消失，除此之外，心电图和心肌酵素皆无明显变化。

There were statistical differences among the ST upslope, downslope, level and no ST-depression groups, while no difference was showed when paired T test was performed.

心电图ST段形态学下移型组内上斜型、下斜型、水平型与ST段正常组比较，差异均有统计学意义。

The change of ST segment electric tension and ejective function have been detected in All patients.

测量患者心绞痛发作时心电图ST段的电压变化，二维超声心动图测定EF值。

Objective:To investigate effect of learning electrocardiogram in practice.

目的 ：探讨在实践中学习心电图的效果。

Experimental results on electrocardiogram data show that the algorithm is effective and reasonable.

通过心电图数据实验验证了算法的有效性和合理性。

In Chapter One, the general knowledge and measure of electrocardiogram are concerned.

在第一章中，介绍了心电图的常识与测量方法。

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。
