Four electrocardiographic scoring systems for the assessment of left ventricular function or presence of myocardial infarction were evaluated in 231 patients with coronary artery disease. Electrocardiographic scores were compared with radionuclide ejection fraction and thallium perfusion studies. The correlation between Wagner's modified QRS score and ejection fraction was only fair (r = -0.60). Askenazi's sum of R wave voltage score correlated poorly with ejection fraction (r = 0.44), as did Gottwik's sum of voltage score from the Frank lead electrocardiogram (r = 0.44). Rautaharju's Cardiac Infarction Injury Score did not reliably predict presence of infarction in the patient group, nor did it correlate well with ejection fraction (r = -0.49). None of the correlations were significantly improved when only patients with a history of a myocardial infarction, a thallium defect compatible with a scar or a diagnostic Q wave were considered. Although Wagner's QRS score correlated best with ejection fraction, all scoring systems had limited clinical usefulness for estimating ejection fraction.
在231例冠心病患者中对四种用于评估左心室功能或心肌梗死存在情况的心电图评分系统进行了评估。将心电图评分与放射性核素射血分数及铊灌注研究结果进行了比较。瓦格纳改良QRS评分与射血分数之间的相关性一般（r = -0.60）。阿斯克纳齐R波电压评分总和与射血分数的相关性较差（r = 0.44），弗兰克导联心电图的戈特维克电压评分总和也是如此（r = 0.44）。劳塔哈尔朱心肌梗死损伤评分不能可靠地预测患者组中梗死的存在情况，与射血分数的相关性也不佳（r = -0.49）。当仅考虑有心肌梗死病史、与瘢痕相符的铊缺损或诊断性Q波的患者时，没有一种相关性得到显著改善。尽管瓦格纳QRS评分与射血分数的相关性最佳，但所有评分系统在估计射血分数方面的临床实用性都有限。
