A dynamic electrocardiographic Holter monitoring study was performed in 32 healthy children (20 males and 12 females, age range 611 years old), without heart disease, according to clinical and noninvasive instrumental examination. We evaluated atrioventricular conduction time (PR), heart rate (HR), ...

Aims and Objectives: To determine whether abdominal obesity is associated with a prolongation of the QT interval corrected for heart rate (QTc) on the electrocardiogram (EKG) in Indian males with normal BMI. Materials and Methods: It was a cross-sectional study involving 100 males with normal ...
Both food and digoxin decreased T-wave amplitude, and digoxin alone or in combination with food decreased QTc. The positive inotropic effect of a 2.5 MJ mixed meal and a loading dose of digoxin in healthy subjects are of similar degree, different mechanism, and are potentiated in combination....
P-wave duration was 76 ms, 100 ms, and 126 ms in females and 62 ms, 98 ms, and 130 ms in males, respectively. We found the QTc (Bazett) to be 371 ms, 420 ms, and 467 ms in females and 344 ms, 389 ms, and 442 ms in males, respectively. Frontal QRS axis was 6°, 53°...

Conclusions Sex difference in QTc originates from shortened QT in adolescent males. Upper normal limits for QTc vary substantially by age and sex, and it is essential to use age- and sex-specific criteria for evaluation of QT prolongation.Pentti M. Rautaharju...
The upper normal limits of corrected QTc were determined by excluding the top 2% from the global distribution charts as follows: Bazett 483 ms, Fridericia 460 ms, Framingham 457 ms, and Hodges 457 ms. Whether for males and/or females, the middle range of HR from 60 to 99 bpm has ...
Finally, 15/17 patients (76.5%) showed a prolonged QTc interval (QTc max >460 ms), which was likely secondary to intraventricular conduction defect or AV block in 13, and only two patients had a normal maximum QTc interval (<440 ms). 3.5. Incomplete Penetrance and Variable Expressivity ...
