    The spatial ventricular gradient, assessed using computerized vectorcardiography, offers precise measurements of ventricular repolarization. This method establishes new normal limits and aids in understanding arrhythmias linked to repolarization desynchronization.

    Area of Science:

    • Cardiology
    • Electrophysiology
    • Medical Imaging

    Background:

    • The ventricular gradient reflects uneven ventricular repolarization.
    • Traditionally assessed in the frontal plane via electrocardiography, its spatial orientation was less understood.
    • Computerized vectorcardiography allows for a more precise evaluation.

    Purpose of the Study:

    • To evaluate the size and spatial orientation of the vector gradient using computerized vectorcardiography.
    • To establish reference values for the spatial ventricular gradient in a normal population.
    • To explore its utility in defining normality and understanding repolarization abnormalities and arrhythmias.

    Main Methods:

    • Computerized vectorcardiography was employed to calculate the spatial vector gradient.

  • Measurements were taken in a control group of 70 normal subjects (mean age 36 ± 21 years).
  • Reference values for amplitude, site, and azimuth were determined.

    • Main Results:

    • Reference values in normal subjects: amplitude 0.092 ± 0.016 mVs, site 38.4° ± 6.1°, azimuth 21.6° ± 8.7°.
    • The size and spatial orientation of the gradient were quantifiable.
    • Distinct subgroups could be identified using site and azimuth values.

    Conclusions:

    • The spatial ventricular gradient provides a novel approach to defining normal limits for ventricular repolarization.
    • It aids in identifying abnormalities in ventricular repolarization.
    • This technique may enhance comprehension of cardiac arrhythmias associated with repolarization desynchronization.
