In the subgroup of patients above 15 years and without beta blocker treatment, the sex effect (female minus male) on QTci interval duration was 17 ms (4.1; 29.9) in LQT1 patients. QTc duration was not different between sex in LQT2 and in LQT3 patients (mean difference 3 ms (21.6; ...
Age trends were apparent for the QTc interval, QRS axis, and indices of left ventricular hypertrophy. Amplitudes in the left precordial leads showed a substantial increase in the older age groups for women, but not for men. Sex-dependent differences were apparent for most ECG parameters. All ...

Heart transplant (HT) patients were analyzed to see whether the QTc depends more on sex of donor or recipient Subjects: 20 male/male (recipient/donor); 21 female/male; 17 female/female; 15 male/female; 23 healthy male; 20 healthy female. Continuous measurement was used over five postural ...
When the QTc interval is "shortened" in response to a decrease in the RR interval (a> -0.079), the QT response is considered normal. When the QTc interval is "lengthened" (a -0.079), the reaction is considered pathological. ;EFFECT: method improves accuracy of detecting the latent ...

Increasing intra-abdominal deposition of fat is closely associated with prolongation of the QTc interval independent of obesity and other cardiovascular risk factors. This may facilitate the development of cardiac arrhythmias and sudden death. Aims and Objectives: To determine whether abdominal obesity is...
Also the mean QRS duration in female was significantly smaller than male (p = 0.03). There were no statistically significant differences in the mean R/T ratio, QTc interval, Tpeak-end duration between subgroups, six postures and three lead (p > 0.05).Postures, electrodes location and cardiac...
