Key result
An automatic two-pass algorithm reliably calculated the QT-interval compared to experienced cardiologists, with a non-significant difference of 3.64 msec, even with major baseline wander.
Why the study?
Does a novel two-pass automatic algorithm accurately measure the QT-interval compared to manual measurement by experienced cardiologists?
Does a novel two-pass automatic algorithm accurately measure the QT-interval compared to manual measurement by experienced cardiologists?
Effect estimate: Mean difference 3.64 msec
p-value: p=n.s.
A novel two-pass algorithm can reliably and automatically calculate the QT-interval beat-to-beat, even in the presence of major baseline wander.

Meij et al. (2002) studied QT-interval measurement (n=20). Automatic two-pass algorithm vs. Eyeball measurements by experienced cardiologists was evaluated on Difference of the QT-interval between the cardiologists and the algorithm (Mean difference 3.64 msec, p=n.s.). An automatic two-pass algorithm reliably calculated the QT-interval compared to experienced cardiologists, with a non-significant difference of 3.64 msec, even with major baseline wander.
