A total of 2,058 vectorcardiograms derived from the conventional 12-lead electrocardiogram (1,555 whites [884 men and 671 women], aged between 16 and 64 years, and 503 Chinese [248 men and 255 women], aged between 18 and 81 years) were analyzed. The results were assessed to demonstrate the importance of the impact of racial variation on vectorcardiographic appearances. The trend of the influence of age and sex on the magnitude and the direction of the QRS and T vectors was found to be similar in both races. In the groups aged younger than 40 years, the magnitude of the maximal spatial QRS vector was found to be greater in whites than in Chinese, while in the groups aged 40 years or older, it was greater in Chinese than in whites. Therefore, this indicates that it is necessary to take racial variation into consideration for interpretation of the derived vectorcardiogram. In conclusion, it has been shown in the present study that derived vectorcardiogram diagnostic criteria should not only be age and sex dependent but also race dependent.
对从常规12导联心电图得出的总共2058份心电向量图进行了分析（其中1555份来自白人[884名男性和671名女性]，年龄在16至64岁之间；503份来自中国人[248名男性和255名女性]，年龄在18至81岁之间）。对结果进行评估以证明种族差异对心电向量图表现影响的重要性。发现年龄和性别对QRS波群和T波向量大小及方向的影响趋势在两个种族中相似。在40岁以下的人群中，发现白人最大空间QRS波群向量的大小大于中国人，而在40岁及以上的人群中，中国人的大于白人。因此，这表明在解释导出的心电向量图时必须考虑种族差异。总之，本研究表明，导出的心电向量图诊断标准不仅应依赖于年龄和性别，还应依赖于种族。
