Abstract

Background— The present study examined pacing site–dependent changes in QT interval and transmural dispersion of repolarization (TDR) and their potential role in the development of torsade de pointes (TdP). Methods and Results— In humans, the QT interval, JT interval, and TDR were measured in 29 pat...
