Gender-affirming hormone therapies (GAHT) were associated with some cardiac repolarization alterations evident on ...

Cardiac aging results in the development of cardiac pathologies. Electrocardiogram (ECG) measures reflect cardiac excitation, conduction, and repolarization.

Other common training-related ECG changes included sinus bradycardia in 61.3%, early repolarization in 24.3%, LV hypertrophy in 10.4% and a PR interval of 200 milliseconds or more in 10.3%.

“Pig heart-in-pig body” accepted parameters included a short pulse rate (PR) interval (50-120 milliseconds [ms]), short QRS duration (70-90 ms), and short QT interval for repolarization (260 ...

About 15% of young athletes with early repolarization will also have an incomplete right bundle branch block, which represents slowing of the electrical impulses within the ventricles and a ...
