ECG Form 1 上图是某试验筛选期收集的EG信息,ECG的检测指标主要有以下6个:PR Interval (PR)、QRS Interval (QRS)、QT Interval (QT)、QTc Interval (QTc)、RR Interval (RR)以及 Heart Rate (HR)。除了以上6个检测指标外,ECG Form还会包含研究者对与检测结果的判定,具体是图中Result Code的部分。这部分有...
EG domain主要收集CRF上心电图（Electrocardiogram）检查的相关测量数据。通常，EG信息在临床试验的筛选期 (Screening)和计划访视 (Scheduled Visits/Folders) 内收集。上图是某试验筛选期收集的EG信息，ECG的检测指标主要有以下6个：PR Interval (PR)、QRS Interval (QRS)、QT Interval (QT)、QTc Interva...

这也可以称为右心房异常。 The QRS complex duration is normal (0.08 sec). The QT/QTc intervals are normal (300/410 msec). However, the QRS complex has anabnormal morphology.The axis is right ward,between +90° and+...
求翻译:The QT interval in the electrocardiogram (ECG) represents the duration of ventricular depolarization and subsequent repolarization. It is measured from the beginning of the QRS complex to the end of the T wave. The 'group-Q-onset' and a 'group-T-wave end' are defined, respectively, ...

The normal QT interval is in the range: Men 390 - 450ms Women 390 - 460ms but it depends on the heart-rate. The QT interval is therefore adjusted to compensate for heart-rate to give QTc. Several compensation formulae are used:
QT intervalT waveventricular depolarizationventricular repolarizationSummary In a normal ECG, only the electrical activity can be seen; mechanical action (contraction) is not registered by the ECG. Intervals are periods of time including waves and complexes. Segments are always measured between waves ...
The normal QT interval is controversial, and multiple normal durations have been reported. In general, the normal QT interval is below 400 to 440 milliseconds (ms), or 0.4 to 0.44 seconds. Women have a longer QT interval than men. Lower heart rates also result in a longer QT interval. ...
QT interval is the time from the start of the Q wave to the end of the T wave, time taken for ventricular depolarisation and repolarisation
