to compare corrected QT interval in normal Egyptian neonates to published values of other ethnic groups. This cross sectional study was conducted on neonates following up in Children's Hospital Ain Shams University, with post natal ages ranging from 8 to 28days (mean 13.91卤3.97days). They were...

normal QT interval Calculate the corrected QT interval (QTc) by dividing the QT interval by the square root of the preceeding R - R interval. Normal = 0.42 s. Causes oflong QT interval myocardial infarction, myocarditis, diffuse myocardial disease ...

The minimum QT interval averaged 261 ± 10 ms for HR> 120 and the maximum 389 ± 9 ms for HR ¤ 60; the corresponding mean value of QTc (i.e., QT corrected for HR) ranged from 388 ±8 for HR¤60 beats/min to 403 ±14 ms for HR> 120 beats/min. The results of the present...
Monitoring the corrected QT interval (QTc) is therefore critical for patient safety. The recent development of smart phone heart monitors (SHM) may allow for easier QTc monitoring. We sought to evaluate the accuracy of an SHM for assessing the QTc, as compared to the standard 12‐lead ECG....
When corrected for heart rate, the QTc interval of pregnant women was not significantly different from that of non-pregnant women, thus suggesting that the average duration of ventricular repolarization is not altered by pregnancy. In contrast, the dynamic process of QT interval adaptation to heart...

The QT interval (V 4 ) and the QT interval corrected with the cubic root were shorter for the nonsporting controls. Three parameters for QT dispersion showed significant differences (p < 0.003) between athletes with disease and all other groups. It is concluded that although significant ...
