The QT interval should be deter- mined as a mean value derived from at least 3–5 cardiac cy- cles (heartbeats), and is measured from the beginning of the earliest onset of the QRS complex to the end of the T wave. The QT measurement should be made in leads II and V5 or V6, ...

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...
Various QT interval variables and heart rate variability parameters were studied in six patients with ventricular fibrillation but without heart disease and compared with findings in 21 normal persons. QT and QT dispersion (QTd) were measured from conventional 12 lead ECGs: for dynamic QT analysis, ...
摘要: QRS duration significantly affects QT measurement, even within the normal range of QRS. Baseline QRS of 100 ms permits less slack than QRS of 70 ms before showing the QT effect of QT-prolonging influences, strengthening the case for substituting JT for QT interval....
The patient was given 20 mg intramuscular ziprasidone for agitation. He developed palpitations and weakness 45 minutes after receiving ziprasidone. His QT interval was prolonged on ECG and returned to baseline after 72 hours. They concluded that performing an ECG before ziprasidone dosing should be ...

Contribution of heart rate to QT interval shortening during exercise The contributions of the intrinsic effect of heart rate and factors other than heart rate, to exercise-induced QT interval shortening were assessed by stud... FANANAPAZIR L,BENNETT D. H,FARAGHER E. B - 《European Heart ...
Tables3and4show percentiles 1st,2nd, 50th, 98th and 99th for heart rate, P, QRS and T frontal axis, overall P and QRS duration, overall P and QT interval and QTc corrected by Hodges, Bazett, Fridericia and Framingham methods for different age groups and both sexes. All global parameters...
In normal sinus rhythm, what does the P-wave, the PR interval, QRS complex, and QT interval reflect? ECG: An ECG, or electrocardiogram, is an electrical readout of the heart which measures the electrical output of all heart chambers during cardiac cycles. ...
