Derived vectorcardiograms from 503 healthy Chinese individuals (248 men and 255 women) were analyzed to determine the normal ranges of scalar and vector measurements in a Chinese population. In both sexes, the magnitude of the maximal spatial QRS and T vectors decreased significantly with age and was significantly smaller in women in all age groups. The results of this study were concordant with the results of previous studies using the Frank lead system in Caucasians, but the derived vectorcardiogram has the advantage of not requiring any leads additional to those used for recording the conventional 12-lead electrocardiogram. In conclusion, it was found that for healthy Chinese individuals there are significant age and sex related influences on the normal ranges of derived vectorcardiograms. Therefore, vectorcardiographic diagnostic criteria for Chinese individuals should be age-related and sex-related.
对503名健康中国个体（248名男性和255名女性）的衍生向量心电图进行分析，以确定中国人群中标量和向量测量的正常范围。在两性中，最大空间QRS和T向量的大小均随年龄显著降低，且在所有年龄组中女性均显著较小。本研究结果与先前在高加索人群中使用Frank导联系统的研究结果一致，但衍生向量心电图具有无需除记录常规12导联心电图所用导联之外的任何额外导联的优势。总之，发现对于健康中国个体，衍生向量心电图的正常范围存在显著的年龄和性别相关影响。因此，中国个体的向量心电图诊断标准应与年龄和性别相关。
