Identifying ST-segment changes in patients with LVH is frequently associated with false-positive diagnoses of acute coronary syndrome
根据 ST段变化诊断LVH患者患急性冠脉综合征时，往往产生假阳性

This study analyzed the ACTIVATE-SF database, a registry of consecutive emergency department STEMI diagnoses from 2 medical centers (411 patients)
本研究分析了ACTIVATE-SF数据库，记录了从2个医疗中心（411例）的急诊科就诊的全部STEMI病人

In patients with anterior territory ST-elevation, using a ratio of ST segment to R-S–wave magnitude >25% as a diagnostic criteria for STEMI significantly improved specificity for an angiographic culprit lesion (true positive) 
在前壁ST段抬高患者，应用ST段与R－S波高度比值大于25％做为STEMI的诊断标准可明显提高阳性血管造影的特异性（真阳性）

Although this rule requires further study in a larger population it may augment current criteria for determining which patients with ECG LVH should undergo PCI
虽然这条规则还需要在更大的人群中做进一步的研究，但它会强化现有的诊断标准，以确定哪些需要经皮冠状动脉介入治疗的心电图有LVH变化的患者
