We for the first time defined the heart vector origin point in a time-coherent global median XYZ bea
Our manuscript "Importance of the Heart Vector Origin Point Definition for an ECG analysis: The Atherosclerosis Risk in Communities (ARIC) study" is published in the Journal Computers in Biology and Medicine !!! We developed a method to identify the heart vector's origin on vectorcardiogram. • Origin of the heart vector corresponds to an isoelectric TP (or TQ) segment on ECG. • Time-coherent global XYZ beat properly describes cardiac electrophysiology, and improves accuracy and reproducibility of global VCG and ECG measurements (e.g. QRS duration, QT interval). • Time-coherent global XYZ beat improves the predictive accuracy of sudden cardiac death biomarkers.
