Abstract
Coronary artery disease (CAD) is one of the leading causes of mortality in the world. Treadmill test is a very useful non-invasive test to diagnose and stratify the risk of CAD. Lead aVR is usually a neglected lead while reading the ECG. We describe a case demonstrating the importance of subtle changes in lead aVR that has got a direct angiographic correlation with left main CAD. Therefore picking up the subtle clues on ECG may help in stratifying the risk and optimal treatment of the patient in a timely fashion.
摘要
冠状动脉疾病（CAD）是全球主要的死亡原因之一。平板运动试验是一种非常有用的无创检查，用于诊断CAD并对其风险进行分层。在解读心电图时，aVR导联通常是一个被忽视的导联。我们描述了一个病例，该病例显示了aVR导联细微变化的重要性，这些变化与左主干CAD有直接的血管造影相关性。因此，在心电图上捕捉细微线索可能有助于及时对患者的风险进行分层并进行最佳治疗。
