In 292 patients with anterior myocardial infarction (MI) and no previous MI the electrocardiographically estimated infarct size was correlated with clinical findings during hospitalization and 3-month follow-up. Patients with ECG-defined transmural MI had a higher incidence of different types of complications, such as congestive heart failure (CHF), hypotension, pericarditis, and a longer duration of hospitalization than patients with nontransmural MI. In a subgroup including 182 patients of the total series, a precordial map containing 24 electrodes was used. The sum of R waves (sigma R), the sum of Q waves (sigma Q), the number of Q waves, and sigma R - sigma Q were calculated 4 days after arrival in hospital to estimate the size of infarction. There was generally a correlation between these ECG variables and different clinical findings, such as incidence of CHF, hypotension, pericarditis, and the duration of hospitalization. It is concluded that the ECG determined infarct size in anterior MI in a majority of patients correlates with the incidence of different types of complications in acute myocardial infarction. In the individual patient, however, the risk of developing complications cannot be predicted by ECG changes.
在292例无前壁心肌梗死（MI）病史的急性前壁心肌梗死患者中，通过心电图估算的梗死面积与住院期间及3个月随访时的临床发现相关。与非透壁性心肌梗死患者相比，心电图确诊为透壁性心肌梗死的患者发生不同类型并发症（如充血性心力衰竭（CHF）、低血压、心包炎）的发生率更高，住院时间更长。在该系列研究的182例患者组成的一个亚组中，使用了包含24个电极的胸前导联心电图。入院4天后计算R波总和（∑R）、Q波总和（∑Q）、Q波数量以及∑R - ∑Q，以估算梗死面积。这些心电图变量与不同临床发现（如CHF、低血压、心包炎的发生率以及住院时间）之间通常存在相关性。得出的结论是，在大多数急性前壁心肌梗死患者中，通过心电图确定的梗死面积与急性心肌梗死不同类型并发症的发生率相关。然而，对于个体患者，不能通过心电图变化预测发生并发症的风险。
