Abstract

When Taran and Szilagyi6 reexpressed the Bazett formula in its commonly used form, they eliminated the seemingly useless step of dividing by 1 second by requiring that RR be expressed in seconds. However, this produced the confusion with regard to the correct unit. Incorporation of the 1-second expression allows the QTc to be expressed in the unit that is both logical and arithmetically correct (namely that of the original QT), and eliminates any requirement regarding the units in which the original QT and RR are measured.
