Abstract：Lead aVR is located on upper right shoulder in frontal plane lead system, overlooking the whole ventricular chamber, and therefore it is called cavity lead. The electrical activity of the whole endocardium can be recorded by lead aVR, which is important for the diagnosis of coronary heart disease. Its diagnostic value is higher than any other unipolar lead or multiple leads, especially for left main coronary artery (LMCA) obstruction and multivessel disease, etc. The contralateral lead of lead aVR, lead “－aVR” arranges frontal plane lead system in order of spatial excitation sequence of the heart. It is more logical and is coincident with the excitation order of the heart, which makes it possible to diagnose inferior wall and high lateral wall acute myocardial infarction. This paper reviews on the clinical application of lead aVR and “－aVR”, combined with overseas literatures in recent years.
