心电图

And 96% for coronary arteries stenosed ≥ 50% respectively.

患者于螺旋CT检查后1周内行冠状动脉造影，以之为标准，观察16层螺旋CT和心电图对于狭窄程度≥50%的冠脉血管诊断的准确性。

The positive rate of ECG rose with the increase of number of stenosed coronary vessel.

The data were analyzed by chi-square test using spss 11.0 statistical analysis software package.results the sensitivity of ecg was 77.2%, specificity 50.0%, false positive rate 50.0%, false negative rate 22.8%, positive predictive value 62.7% and negative predictive value 66.8%.the positive rate of ecg rose with the increase of number of stenosed coronary vessel.

在选择性冠状动脉造影的639例住院患者中，对常规心电图检查进行chd诊断价值的分析比较。并使用spss 11.0统计软件分析包对数据进行r×c表x2检验。结果ecg检查的敏感性为77.2%，特异性为50.0%，假阳性率为50.0%，假阴性率为22.8%，阳性预测值为62.7%，阴性预测值为66.8%。

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.

对286例有自觉症状如胸闷、心悸、乏力等病史做常规心电图检查，并对其中26例ST段平展患者做活动平版运动实验及血清钙检测。

Methods: a comprehensive analysis of 20 cases with acute left ventricular failure as the first manifestations of acute subendocardial myocardial infarction patients with a history of 20 cases and clinical characteristics, according to ECG, dynamic changes of enzymes, Killip classification of cardiac function and cardiac color report indicators of cardiac function, acute acute subendocardial myocardial infarction with acute left heart failure occurred in the characteristics and causes.

综合分析20例以急性左心衰竭为首发表现的急性心内膜下心肌梗死20例病人的病史和临床特点，根据心电图、心肌酶的动态变化、 Killip 心功能分级和心脏彩超报告的心功能指标，探讨急性急性心内膜下心肌梗死发生急性左心衰竭的特征和原因。

94 positive patients without finishing submaximal and showing ending symptoms were divided into male group and femal group. Their ECG, exercise ability and clinical symptom were analyzed and compared with the part patients CAG results.

将运动试验阳性中出现终止指征没完成次极量的94例患者分为男、女两组，分析其心电图、运动能力、临床症状等，并和部分患者的冠状动脉造影结果对照。

Methods 53 patients with paroxysmal supraventricular tachycardia were given incremental doses of adenosine intravenously during sinus rhythm before electrophysiological study.

对53例阵发性室上性心动过速患者在窦性心律下经外周静脉推注递增剂量的腺苷后观察体表心电图上房室传导时间的变化。

The core result conforms to TCM chronomedicine theory that "the cardiacpatiens feel surgeless in the morning, day is better while night is worse",which is proved to be true in science. The result combines modern Holterelectrocardiographic indicators, Zi wu liu zhu time rule and zangfusyndrome differentiation.

研究的核心结果与中医&心病者，日中慧，夜半甚，平旦静&的理论不谋而合，证明了中医时间医学&心病者，日中慧，夜半甚，平旦静&理论的科学性，并把现代动态心电图的心电学指标与中医子午流注时辰规律、脏腑辨证结合起来。

All patients had syncopal attacks, 1 complicated with hearing obstacle, 8 in association with clear inducing factors, but 2 at rest or sleep. 23 patients had long QTc, S congenital patients had special ECG characteristics.

所有患者均有晕厥症状，1例伴听力障碍，8例症状发作前有明确的诱发因素，2例在休息或睡眠时发作。22例QTc延长，8例原发性LQTS患者心电图具特异性改变。

Ideo A is a continuous telemetric recording demonstrating dynamic ST-segment eleation oer a period of 6 minutes and 30 seconds (but accelerated to play in 37 seconds).

图像A是，持续遥控心电监护纪录到的一个动态ST段抬高的心电图，持续时间超过6分钟30秒（但是从37秒开始症状加重）。

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.
