As the interval between QRS waves and T wave in ECG, QT interval represents the depolarization of ventricle.
QT间期指心电波形中QRS波起点到T波终点这一段所对应的时间间隔，代表心室去极化过程。
The ST-T segment changes and QT interval abnormalities are the common indices to measure the ventricular repolarization inconsistencies in clinical practice and epidemiological surveys.
ST-T段改变和QT间期异常是目前临床上和流行病学调查研究中常用的衡量心室复极不一致性的指标。
In this article are discussed the etiology, pathogenesis, Clinical and ECG manifestation as well as treatment of the familial long q-t interval syndrome through census of familial systems.
本文通过二例及家系发病调查，对家族性q—t间期延长综合征的病因、发病机理、临床、心电图表现及治疗进行了讨论。
t Well, let's take a small time interval, delta t.
来取很小的时间间隔△
Usually, T should be about 3000 times larger than the time interval, not too small and not infinite, so that the wet zenith delay can be modeled correctly.
是所取状态未知数时间间隔的3000倍左右，不能太小，又不能趋于无穷大，以。
T he effectiveness of interval velocity time-depth conversion processing is mainly dependent on the correctness and rationality of the built velocity model of ti me-depth conversion.
层速度时深转换处理的效果，主要取决于所建立的时深转换速度模型的正确及合理性。
T he effectiveness of interval velocity time-depth conversion processing is mainly dependent on the correctness and rationality of the built velocity model of ti me-depth conversion.
层速度时深转换处理的效果，主要取决于所建立的时深转换速度模型的正确及合理性。
