背景：由于额面导联的常规显示(即，无序)，导联aVR导联位于-150度，这可能会阻碍两位有经验的年轻临床医生在心电检查中所做的努力，并有被完全忽视的风险。方法：回顾有关aVR和-aVR导联的作用以及额部导联在心电图中的应用历史的研究。结果：在系统分析时，导联aVR，尤其是导联aVR，提供了有用的信息。此外，如果按照aVL、1、-aVR、11、aVF和111的解剖逻辑顺序检查aVR导联，则更容易理解12导联心电图的额面。这种“全景”或“有序”的展示在瑞典等国很常见，但在美国却很少见。结论：以aVL导联开始，111导联结束的顺序显示肢体导联，可以提高心电图的判断力，30°aVR导联可以理想地显示许多心电图改变。
Background: It is possible that efforts in ECG review by both young experienced clinicians are currently discouraged-and risk to be completely dismissed-by the conventional (ie, disorderly) display of the frontal plane leads, with lead aVR at -150degrees. Methods: We reviewed studies on the usefulness of leads aVR and -aVR as well as on the history of the frontal leads in electrocardiography. Results: Lead aVR and particularly, lead -aVR, provide useful information when systematically analyzed. in addition, if lead -aVR is examined in its anatomically logical sequence, ie, aVL, 1, -aVR, 11, aVF, and 111, the frontal plane of the 12-lead ECG is more easily understood. This "panoramic" or "orderly" display is in common use in countries such as Sweden, but it is rarely seen in the United States. Conclusions: ECG interpretation would be enhanced by displaying the limb leads in an orderly arrangement that starts with lead aVL and ends with lead 111, and many ECG changes would be ideally displayed by a lead -aVR at 30degrees.
