Clinical uses of electrocardiographic lead aVR.
Electrocardiographic lead aVR, an augmented unipolar limb lead, for the most part has been ignored in clinical practice. Lead aVR, however, can be useful in diagnosing and determining prognosis in a variety of cardiovascular conditions, including myocardial infarction, myocardial ischemia, conduction disturbances, supraventricular arrhythmias, acute pericarditis, and pulmonary emboli. Careful attention to lead aVR, as well as the other 11 leads of the standard electrocardiogram, can be rewarding to the physicians caring for patients with cardiovascular disease.
