    Abstract:
    As an important electrophysiological parameter that reflects cardiac depolarization and repolarization process, ventricular repolarization duration has been drawing growing attention. It is influenced by several physiological and pathological factors and associated with several cardiac diseases. We studied repolarization duration variability (RDV) and dependence of RTm/RR among normal subjects of different age-groups, as well as between normal subjects and subjects with cardiac diseases. It was found that RDV and dependence of RTm/RR are related to age. There are significant differences in the slope of RTm/RR, coherence, CV ratio and RDV between normal subjects and subjects with cardiac diseases. The RDV and dependence of RTm/RR can be employed in providing a more useful evaluation of cardiac disease and function in clinical care.
