Abstract :
Heart rate variability studies have been used to provide a wide array of diagnostic information on the behavior of the heart. Additional information can be gained through the analysis of the temporal differences in ventricular repolarization, as seen in the QT interval. Methods of analysis of this interval are proposed, in addition to a physiological basis for their relevance
