In a population-based study, the routine 12-lead electrocardiogram was found to have a high negative predictive value for detecting left ventricular (LV) systolic dysfunction. Withholding echocardiography in persons without major electrocardiographic abnormalities, however, would result in a considerable underestimation of LV systolic dysfunction (sensitivity only 54%); thus, echocardiography remains an essential tool for detecting LV systolic dysfunction in population-based studies.
在一项基于人群的研究中，发现常规12导联心电图对检测左心室（LV）收缩功能障碍具有较高的阴性预测价值。然而，对于无重大心电图异常的人群不进行超声心动图检查，将导致LV收缩功能障碍被严重低估（敏感性仅为54%）；因此，在基于人群的研究中，超声心动图仍然是检测LV收缩功能障碍的重要工具。
