It has been suggested that the JT rather than QT interval properly reflects repolarization duration in ventricular conduction defects (VCD). The authors examined the influence of QRS duration on the JT and QT intervals in 20,687 normal adult subjects and 2,865 subjects with various categories of VCD. Estimates for coefficients for multiple regression of QRS duration on QT and JT intervals combined with a correction term for heart rate (HR) were determined for each VCD category. QRS duration… CONTINUE READING
