Heart Vector Origin Point Detection and Time-Coherent Median Beat Construction

Erick Andres Perez Alday, Larisa Tereshchenko

The algorithm finds the heart vector origin point and constructs the time-coherent median beat. VCG origin point is defined as the electrically quiet or isoelectric state of the heart when the heart vector does not move in 3D space.
