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 ...

This change produces a decrease in the length of the QTc interval. There is a lack of correlation QTc and serum calcium. The interval from the qt to the apex of the T wave can be measured most precisely and shows the best correlation with the Ca level (Fig. 94-29c). First degree ...
“This certainly highlights the need to monitor the health of preterm survivors across their lifespan, and more research needs to be done,” he said. “This also emphasizes the need to forewarn the ELBW men and promote healthy aging so they may proactively mitigate...

Results: Significant age trends were present in, for example, P-wave duration, QTc interval, and frontal QRS axis, with concomitant changes of R amplitudes in the extremity leads. Sex differences existed for heart rate, interval durations, the Sokolow and Cornell indices, and QRS and ST-T ...
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...

In this article, we report a case of COVID-19 patient who developed polymorphic ventricular tachycardia with torsade de pointes morphology with normal QTc interval in the setting of fever. An 81-year-old woman was admitted with symptoms of COVID-19. She was treated with hydroxychloroquine, ...
