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

Erick Andres Perez Alday, Larisa Tereshchenko

An appropriate selection of the heart vector origin point defines the ECG’s baseline, which then affects all subsequent ECG measurements. We introduce software capable of automatically identifying the heart vector origin point and constructing a tim…
