对231例冠心病患者进行了四种心电图评分系统的评价。将心电图评分与放射性核素射血分数和铊灌注研究进行比较。瓦格纳改良QRS评分与射血分数之间的相关性仅为一般（r = -0.60）。Askenazi的R波电压评分总和与射血分数相关性较差（r = 0.44），Gottwik的Frank导联心电图电压评分总和也是如此（r = 0.44）。Rautaharju的心肌梗死损伤评分不能可靠地预测患者组中是否存在梗死，也不能与射血分数良好相关（r = -0.49）。当仅考虑有脑梗死病史、铊缺陷伴瘢痕或诊断性Q波的患者时，相关性无显著改善。虽然瓦格纳的QRS评分与射血分数相关性最好，但所有评分系统对估计射血分数的临床实用性有限。
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 niyocardial 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.
