Sex and age differences of ventricular gradient (G) were analyzed and normal ranges were determined in normal Japanese subjects (120 men and 74 women), whose resting heart rate was within the range of 65 to 75 beats/min. Women showed a larger Z component in AT and a smaller Y and larger Z component in G than men. The common trend in age differences was a decrease in Y component of G in both men and women. The ranges obtained in the present study can be applied in automatic VCG analysis, in particular for the differentiation of primary and secondary ST-T changes.
