In a retrospective study of 304 patients with acute transmural myocardial infarction admitted to the coronary care unit, 22 percent (67 patients) exhibited low voltage on their electrocardiograms within 72 hours of admission. The course of hospitalization of these patients was compared with an equal number of consecutive patients with transmural infarctions and normal electrocardiographic voltages. Among the patients with low voltage, there was a significantly higher incidence of previous infarction or present extensive infarction, congestive heart failure, and cardiogenic shock. This group of patients also demonstrated a markedly higher mortality. This study substantiates the clinical impression that acute myocardial infarction complicated by a low-voltage ECG implies a poor prognosis. It is speculated that this electrocardiographic pattern may reflect decreased ventricular performance as a result of widespread myocardial damage.
在一项对入住冠心病监护病房的304例急性透壁性心肌梗死患者的回顾性研究中，22%（67例患者）在入院72小时内心电图显示低电压。将这些患者的住院病程与同等数量的连续透壁性梗死且心电图电压正常的患者进行比较。在低电压患者中，既往梗死或当前广泛梗死、充血性心力衰竭和心源性休克的发生率显著更高。这组患者的死亡率也明显更高。本研究证实了临床印象，即急性心肌梗死合并心电图低电压意味着预后不良。据推测，这种心电图模式可能反映了广泛心肌损伤导致的心室功能下降。
