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.
分析了正常日本受试者（120名男性和74名女性）的心室梯度（G）的性别和年龄差异，并确定了正常范围，这些受试者的静息心率在65至75次/分钟之间。与男性相比，女性在心房颤动（AT）中显示出更大的Z分量，在G中显示出更小的Y分量和更大的Z分量。年龄差异的共同趋势是男性和女性的G的Y分量均降低。本研究中获得的范围可应用于自动心室心电图（VCG）分析，特别是用于鉴别原发性和继发性ST-T改变。
