In 587 patients with acute myocardial infarction (AMI) and no previous MI, electrocardiographically estimated infarct size was related to three-month mortality. Mortality was found to be higher in patients with transmural MI (Q or R-wave changes in standard ECG) than in patients with subendocardial infarction (ST-T wave changes in standard ECG). In patients with anterior MI, precordial mapping with 24 chest electrodes was analyzed four days after arrival in hospital (n = 197). Neither the sum of R-waves, the sum of Q-waves, nor the number of Q-waves correlated significantly with early mortality, although there was a trend towards higher mortality among patients with more pronounced ECG changes. Finally, in patients with inferior AMI (n = 230), neither the sum of R-waves nor the sum of Q-waves in leads II, III and aVF on the fourth day influenced three-month mortality. However, when subtracting the sum of Q-waves from the sum of R-waves, there was a significant correlation between the estimated infarct size and the early mortality.
在587例急性心肌梗死（AMI）且既往无心肌梗死病史的患者中，心电图估算的梗死面积与3个月死亡率相关。发现透壁性心肌梗死（标准心电图出现Q波或R波改变）患者的死亡率高于心内膜下梗死（标准心电图出现ST - T波改变）患者。在前壁心肌梗死患者中，197例患者在入院4天后采用24个胸电极进行胸前区心电图描记分析。尽管心电图改变越明显的患者死亡率有升高趋势，但R波总和、Q波总和及Q波数量均与早期死亡率无显著相关性。最后，在下壁心肌梗死患者（n = 230）中，第4天II、III和aVF导联的R波总和及Q波总和均不影响3个月死亡率。然而，当用R波总和减去Q波总和时，估算的梗死面积与早期死亡率之间存在显著相关性。
