OBJECTIVES Understanding why prolonged Bazett-corrected QT interval (QTc) is a risk factor for mortality is difficult, because QTc is positively correlated with heart rate. To optimally distinguish the effects of QT interval and heart rate on mortality, QT interval and heart rate were modeled separately and jointly in Pima Indians. METHODS The effects of… CONTINUE READING
