In 270 patients with acute inferior wall myocardial infarction (MI) and no previous MI, Q- and R-wave changes in leads II, III, and aVF in a 12-lead standard ECG were related to the clinical course during hospitalization and 3-month follow-up. Patients with ECG-defined transmural MI showed a higher incidence of tachycardia, high degree of AV block, congestive heart failure (CHF), and pericarditis than patients with nontransmural MI. In a subgroup including 226 patients, the series was divided into quartiles according to the sum of Q- and R-wave changes in leads II, III, and aVF 4 days after arrival in hospital. A weak correlation between ECG-determined infarct size and the incidence of complications such as congestive heart failure (CHF), need for furosemide, and pericarditis, as well as the duration of hospitalization was observed. It is concluded that ECG-determined infarct size from leads II, III, and aVF in inferior MI is associated with the clinical course, although it cannot predict the outcome in the individual patient.
在270例急性下壁心肌梗死（MI）且既往无MI病史的患者中，12导联标准心电图中II、III和aVF导联的Q波和R波变化与住院期间及3个月随访时的临床病程相关。与非透壁性MI患者相比，心电图确诊的透壁性MI患者心动过速、高度房室传导阻滞、充血性心力衰竭（CHF）和心包炎的发生率更高。在一个包含226例患者的亚组中，根据入院4天后II、III和aVF导联Q波和R波变化的总和将该系列患者分为四分位数。观察到心电图确定的梗死面积与充血性心力衰竭（CHF）、使用速尿的必要性、心包炎等并发症的发生率以及住院时间之间存在弱相关性。结论是，下壁心肌梗死时II、III和aVF导联心电图确定的梗死面积与临床病程相关，尽管它不能预测个体患者的预后。
