In a retrospective study of patients with acute myocardial infarction admitted to a coronary monitoring unit in 1971 12 per cent (39 patients) had low voltage electrocardiograms within 72 hours of admission. Of these, 7 patients (18%) died while in hospital and a further 9 (23%) died within one year of their infarction. Of the 23 patients who survived, 16 were severely incapacitated by their symptoms at the one-year follow-up. A low voltage electrocardiogram in association with acute myocardial infarction appears to imply a poor prognosis in terms of both mortality and morbidity, independently of other prognostic indices.
在一项对1971年入住冠心病监护病房的急性心肌梗死患者的回顾性研究中，12%（39例患者）在入院72小时内出现心电图低电压。其中，7例（18%）患者住院期间死亡，另有9例（23%）在心肌梗死后一年内死亡。在存活的23例患者中，16例在一年随访时因症状而严重丧失劳动能力。与急性心肌梗死相关的心电图低电压似乎意味着在死亡率和发病率方面预后不良，且独立于其他预后指标。
