Three automatic approaches to the ventricular repolarisation duration measurement (the RTapex, RTend threshold and RTend fitting methods) were compared on computer-generated and real ECG signals in relation to their reliability in presence of the most common electrocardiographic artefacts (i.e. additive broad band noise, additive and multiplicative periodical disturbs). Simulations permitted to evaluate the amount opf RT beat-to-beat variability induced by the artefacts. The RTend threshold method performed better than the RTend fitting one, thus the latter should be used with caution when the RT end variability is addressed

Abstract

Three automatic approaches to the ventricular repolarisation duration measurement (the RTapex, RTend threshold and RTend fitting methods) were compared on computer-generated and real ECG signals in relation to their reliability in presence of the most common electrocardiographic artefacts (i.e. additive broad band noise, additive and multiplicative periodical disturbs). Simulations permitted to evaluate the amount opf RT beat-to-beat variability induced by the artefacts. The RTend threshold method performed better than the RTend fitting one, thus the latter should be used with caution when the RT end variability is addressed
