Introduction: Ventricular pacing (VP) may impact the accuracy of QT interval measurement, as it increases the QT by increasing the QRS duration amongst other mechanisms. We aimed to …

2022年1月1日 · In this review, we discuss the components of QT interval assessment for arrhythmogenic risk including arrhythmogenic QT prolongation, methods for adjusting the QT …

The Corrected QT Interval (QTc) adjusts the QT interval correctly for heart rate extremes.

2019年11月1日 · We proposed a new, simple formula for QT estimation in RV pacing. JT interval in paced complexes is highly HR dependent and is not accurate for QT assessment. The new …

Worried about QT interval prolongation? This online evidence based resource will help guide you how to measure the QT interval and calculate the QTc value with an easy to use calculator …

Results: At a mean spontaneous heart rate of 66 bpm (SD ±8), the mean difference in QTc between the ventricular paced and nonpaced QRS was 48.27 ms (95% CI = 32-64.6 ms, p < …

The aim of the study was to determine whether QTc prolongation in VP (ventricular pacemaker) patients is associated with increased risk of fatal arrhythmia or other cardiac complications and …

2017年9月15日 · We aimed to validate the currently available formulas for QT determination during VP and to compare their abilities in predicting the occurrence of CA (atrial fibrillation …

The paced QTc interval appears to be a more useful marker in predicting bad prognosis than does the intrinsic QTc interval in patients with indications for a permanent pacemaker.

2003年1月20日 · In rabbit experiments, switching from endocardial to epicardial pacing produced a net increase in QT interval and TDR by 17±5 and 22±5 ms, respectively (n=6, P <0.01), …
