Relationship between Beat‐to‐Beat Variability of RT‐Peak and RT‐End Intervals in Normal Controls Patients with Anxiety and Patients with Cardiovascular Disease

摘要

Some studies suggest that it is important to take the end of “T” wave to quantify QT‐interval variability, which signifies cardiac repolarization lability, as there is substantial and important information beyond the peak of the T wave on the surface electrocardiogram.
