Do Fridericia and Framingham QT correction formulae improve prediction of 30-day and 1-year mortality compared to the Bazett formula?
Fridericia and Framingham formulae should be preferred over Bazett for QT correction to better predict mortality and avoid falsely identifying dangerous QTc prolongation.
Fridericia and Framingham correction formulae showed the best rate correction and significantly improved prediction of 30-day and 1-year mortality. With current clinical standards, Bazett overestimated the number of patients with potential dangerous QTc prolongation, which could lead to unnecessary safety measurements as withholding the patient of first-choice medication.
