The 3 orthogonal lead electrocardiogram has been evaluated with computer assisted interpretation in 20 patients with acute pulmonary embolism confirmed by pulmonary angiography. Initial 3-lead electrocardiographic abnormalities were found to be at least as helpful as the 12-lead electrocardiogram in supporting the clinical diagnosis. In addition, however, sequential changes in both the maximum QRS and T vector orientations in frontal and transverse planes were more often apparent than any sequential changes in the 12-lead electrocardiogram. While no specific 3 lead electrocardiographic criterion for pulmonary embolism could be determined, this technique was more helpful than conventional methods in following serial electrocardiographic changes in patients with this condition.
对20例经肺血管造影确诊为急性肺栓塞的患者，采用计算机辅助解读评估了3导联正交心电图。结果发现，初始3导联心电图异常在支持临床诊断方面至少与12导联心电图一样有帮助。然而，除此之外，额面和横面最大QRS波群和T向量方向的连续变化比12导联心电图的任何连续变化更常出现。虽然无法确定肺栓塞的特异性3导联心电图标准，但在追踪该疾病患者的系列心电图变化方面，这项技术比传统方法更有帮助。
