Does automatic QTc-Bazett measurement combined with QTc-Fridericia calculation reliably identify postoperative patients who require manual QTc measurement?
A two-step automatic QTc calculation method can reliably screen postoperative patients to determine who needs manual QTc confirmation.
Automatic QTc-Bazett measurement, if abnormal, associated with calculation of QTc-Fridericia reliably identifies patients in whom manual QTc measurement must be performed to confirm postoperative prolonged QTc interval.
Charbit et al. (Mon,) studied this question.
