Ventricular gradient (G) ranges differ between sexes and change with age. These findings aid in differentiating ST-T changes using automated vectorcardiography (VCG) analysis.

Area of Science:

  • Cardiology
  • Physiology
  • Medical Imaging

Background:

  • The ventricular gradient (G) provides insights into cardiac electrical activity.
  • Understanding normal ranges for G is crucial for accurate clinical interpretation.
  • Previous studies have not comprehensively analyzed sex and age-specific G variations.

Purpose of the Study:

  • To determine normal ranges for the ventricular gradient (G) in a Japanese population.
  • To investigate sex-specific differences in G components.
  • To analyze age-related trends in G components.

Main Methods:

  • Analysis of ventricular gradient (G) in 120 men and 74 women.
  • Subjects had resting heart rates between 65-75 beats/min.
  • Determination of normal ranges and comparison between sexes and age groups.

Main Results:

  • Women exhibited a larger Z component in the spatial angle (AT) and different Y and Z components in G compared to men.
  • A consistent age-related decrease in the Y component of G was observed in both sexes.
  • Normal ranges for G were established for the studied population.

Conclusions:

  • Established normal ranges for ventricular gradient (G) can be applied to automated vectorcardiography (VCG) analysis.
  • These ranges are particularly useful for distinguishing primary from secondary ST-T changes.
  • Sex and age are significant factors influencing ventricular gradient (G) values.
