Methodology of QT-Interval Measurement in the Modular ECG Analysis System (MEANS)
Annals of Noninvasive Electrocardiology
Background. QT prolongation as can be induced by drugs, signals the risk of lifethreatening arrhythmias. The methodology of QT measurement in the Modular ECG Analysis System MEANS is described. Methods. In the simultaneously recorded leads of the standard 12-lead ECG, the QRS complexes are detected by a spatial velocity function. They are typed as dominant or non-dominant, and a representative complex per lead is obtained by averaging over the dominant complexes. QRS onset and T end aredoi:10.1111/j.1542-474x.2008.00261.x pmid:19143743 fatcat:i3mvhag7vzfgho5kwkklnvcyuy
