The significance of a priminent S wave leads I and/or V6 in electrocardiograms of persons aged 30 years or over was studied in 1249 patients who died at hospital. A priminent S wave was found in 4.1% in lead I, in 10.5% in lead V6, and in 2.3% simultaneously in both leads in 171 patients in whom no pulmonary or cardiac disease was observed at autopsy. The occurrence of a prominent S wave in leads I and/or V6 was significantly more frequent in patients with cardiopulmonary diseases than in those without these conditions. This ECG sign was not, however, highly specific for any disease. S wave patterns were frequently found in conditions causing right ventricular overload. The SI and/or SV6 patterns were also common in patients with myohy. It is concluded that a prominent S wave in lead I alone or together with lead V6 in ECGs of middle-aged and elderly patients suggests the presence of a disease affecting the pulmonary criculation or the left ventricle of the heart.
对1249例在医院死亡的患者进行研究，以探讨30岁及以上人群心电图中I导联和/或V6导联出现明显S波的意义。在171例尸检未发现肺部或心脏疾病的患者中，I导联出现明显S波的比例为4.1%，V6导联为10.5%，两个导联同时出现明显S波的比例为2.3%。心肺疾病患者中I导联和/或V6导联出现明显S波的情况明显多于无这些疾病的患者。然而，这种心电图表现对任何疾病都没有高度特异性。S波形态常见于导致右心室负荷过重的情况。SI和/或SV6形态在心肌疾病患者中也很常见。结论是，中老年患者心电图中单独I导联或I导联与V6导联同时出现明显S波提示存在影响肺循环或左心室的疾病。
