Lead aVR--the neglected lead.
The aVR is often neglected lead. It is an unipolar lead facing the right superior surface. As all the depolarisations are going away from lead aVR, all waves are negative in aVR (P, QRS, T) in normal sinus rhythm. In dextrocardia, (True and technical) the p is upright in aVR. The lead aVR is a very important lead in localisation of Coronary Artery Disease. In the presence of anterior ST elevati...
متن کاملElectrocardiographic applications of lead aVR.
Lead aVR, 1 of 12 electrocardiographic leads, is frequently ignored in clinical medicine. In fact, many clinicians refer to the 12-lead electrocardiogram (ECG) as the 11-lead ECG, noting the commonly held belief that lead aVR rarely offers clinically useful information. In this report, we discuss the findings in lead aVR, which are potentially of value, including ST-segment elevation in the pat...
متن کاملUtility of lead aVR for identifying the culprit lesion in acute myocardial infarction.
BACKGROUND Lead aVR is a neglected, however, potentially useful tool in electrocardiography. Our aim was to evaluate its value in clinical practice, by reviewing existing literature regarding its utility for identifying the culprit lesion in acute myocardial infarction (AMI). METHODS Based on a systematic search strategy, 16 studies were assessed with the intent to pool data; diagnostic test ...
متن کاملA Sign to Heaven: aVR Lead Elevation and Myocardial Infarction
Isolated ST-segment elevation only in the aVR lead, reflecting an acute myocardial infarction due to a left main coronary artery occlusion, was ignored as part of physicians' training in emergency medicine for a long time. The recognition of aVR lead elevation is becoming more accepted as a mandatory diagnostic tool, in particular for physicians working at emergency departments. We report a typ...
متن کاملLead aVR, a mostly ignored but very valuable lead in clinical electrocardiography.
In this issue of the Journal, Yamaji et al. (1) report on the use of lead aVR in the diagnosis of acute left main coronary artery (LMCA) obstruction. More specifically, the investigators compare the behavior of the ST-segment in lead aVR with lead V1 in that situation. They report that in LMCA occlusion, more ST-segment elevation is present in lead aVR compared to lead V1. They also found a rel...
