| Abstract |
|
The 12-lead electrocardiogram (ECG) is an inexpensive bedside tool that most physicians use to make rapid diagnoses such as acute myocardial infarction (AMI), arrhythmia, and conduction abnormalities. Although each lead in the ECG represents electronic information from specific portions of the heart, lead aVR, an augmented unipolar limb lead, is frequently ignored. The aVR lead provides excellent information from the right portion of the heart, including the outflow tract of the right ventricle and basal portion of the septum. In this report, we discuss ST segment elevation changes in lead aVR of serial ECGs in emergency room patients with chief complaints of syncope and chest discomfort. |
