The QT interval is the time from the beginning of the QRS complex, representing ventricular depolarization, to the end of the T wave, resulting from ventricular repolarization. The normal QT interval ...

The maternal heart significantly adapts to the circulatory needs of pregnancy, but the effect of pregnancy on ventricular repolarization is poorly understood. The aim of this study was to quantify ...

What is the best way to estimate the QT interval on the ECG? What is the equation for QTc? A good way to estimate if the QT interval prolonged is by checking its relation to the R-R interval. If the ...

Having access to less intrusive QT interval measurement with flexibility around the time and place of the appointment is important 3.1 Psychiatric service user experts explained that it is important ...

Similarly, subjects with an increased QT dispersion (QTd), which may mirror discrepant repolarization characteristics of different areas of the heart, show an increased cardiovascular mortality and ...

The diagnostics advisory committee considered evidence on KardiaMobile 6L for measuring QT interval from several sources, including an early value assessment report, cost and resource use report and ...
