QT dispersion as an attribute of T-loop morphology.

Journal: :Circulation 1999

J A Kors G van Herpen J H van Bemmel

BACKGROUND The suggestion that increased QT dispersion (QTD) is due to increased differences in local action potential durations within the myocardium is wanting. An alternative explanation was sought by relating QTD to vectorcardiographic T-loop morphology. METHODS AND RESULTS The T loop is characterized by its amplitude and width (defined as the spatial angle between the mean vectors of the...

Individual QT-R-R relationship: average stability over time does not rule out an individual residual variability: implication for the assessment of drug effect on the QT interval.

Journal: :Annals of noninvasive electrocardiology : the official journal of the International Society for Holter and Noninvasive Electrocardiology, Inc 2005

Fabrice Extramiana Pierre Maison-Blanche Fabio Badilini Philippe Beaufils Antoine Leenhardt

BACKGROUND Universal QT correction formulae have been shown to under or overcorrect the QT interval duration. Individual QT-R-R modeling has been proposed as a preferable solution for heart rate correction of QT intervals. However, the QT-R-R relationship stability over time needs to be evaluated. METHODS The present report is part of randomized, double-dummy, and placebo-controlled 4-way cro...
