Objective To study the value of the product of voltage and duration of QRS in diagnosing the left ventricular hypertrophy in primary hypertension.

内容摘要：目的探讨QRS电压与时间乘积诊断高血压、左室肥厚的敏感性、特异性及准确性。

Once these conditions have been excluded, any slurring or notching at the junction between the QRS and the ST segment in inferolateral leads can be an important diagnostic sign for detecting high-risk persons who have a history of unexplained syncope or a family history of sudden death at a young age.

当这些情况都被排除，如果还出现粗钝或前导联QRS-ST段的切记，则对于患者可能具有一个不期晕厥或者具有年轻时突然死亡的家族史是有诊断意义的。

Twenty one patients with the first Q wave type acute anterior or inferior myocardial infarction undergone invasive left ventriculography and coronary angiography were scored with QRS scoring system.

对21例做过左室和冠状动脉造影的首次发生Q波型急性前壁或下壁心肌梗塞患者采用Wagner心电图记分法进行心电图QRS记分。

本文报道不同年龄和性别几项常用的QRS波群复合振幅正常标准，供诊断参考。

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。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
