Diurnal pattern of QTc interval: How long is prolonged?: Possible relation to circadian triggers of cardiovascular events Objectives. This study sought to evaluate the range and variability of the QT and corrected QT (QTc) intervals over 24 h and to assess their pattern and re... Janos,...
To better understand it, we analyzed the QTc interval duration in patients w... Vrtovec,B. - 《Circulation》 被引量: 385发表: 2003年 Risk for life-threatening cardiac events in patients with genotype-confirmed long-QT syndrome and normal-range corrected QT intervals. This study was designed...
Patients with WS have a mean QTcB in the normal range but higher than controls, and a higher than expected frequency of QTc≥460ms compared to the general population. HR is also higher in WS and contributes modestly to the WS QTcB prolongation. Future studies are needed to assess if these...

A wide range of observational studies has investigated the association between QTc interval and CVD morbidity and mortality. Our results align with a recently published meta-analysis that found a significant association between prolongation of the QTc interval and CVD morbidity and mortality in the gene...
Discontinuation of a subject from a clinical trial should be considered if there is a marked prolongation of the QT/QTc interval during treatment with the study drug, especially if the measurement is obtained from more than one ECG. While increases in QT/QTc to 500 ms or of 60 ms over ...

(n = 50, until day 3) or subsequent normothermia (n = 44, day 4–7)) in 33 neonates from 6 publications. The median (range) of QTc intervals during TH was 508 (430–678), and 410 (317–540) ms afterwards (difference 98 ms, or +28 ms/°C decrease). Four additional cohorts ...
Fourty of them (74%) had a normal QTc interval confirmed by Holter ECG recording, while 14/54 (26%) showed a prolonged QTc interval at Holter ECG. Overall, 32 patients from both group I and II had a prolonged QTc interval (mean 475±33 ms) assessed by Holter ECG recording and were ...
