“…Although many articles mentioned importance of lead aVR, we should not rely on the lead aVR solely. 7 To know the importance of lead aVR is important, but V1 had a stronger impact for showing the differentiation of TC from anterior myocardial infarction in our case.…”

Our patient was a 76‐year‐old woman with a history of hypertension and a major depressive disorder who presented to the hospital with a sudden onset of dizziness followed by chest discomfort. ECG findings revealed that there was no ST‐segment elevation in V1 and ST‐segment elevation in V2‐V6. Echocardiography revealed left ventricular wall motion abnormalities. ST‐segment elevation in anterior leads except V1 lead which caused us to suspect Takotsubo‐cardiomyopathy. We confirmed the diagnosis after performing coronary angiography and left ventriculography. Clinicians should suspect Takotsubo‐cardiomyopathy from this typical ECG finding.

“…A late R-wave amplitude greater than or equal to 1.5 mm in lead aVR is found to be more commonly present in patients with APE than without [11]. This sign indicates that the depolarization vector of the QRS terminal portion points to the right superior possibly because of RV enlargement or strain.…”

“…Lead aVR is often described as the "neglected lead", because it points to a vector away from the direction of left ventricular depolarization, and is therefore often assumed to carry little diagnostic information until recent years [1] . Mechanisms proposed to account for ST-segment elevation in lead aVR include transmural basal septal ischemia, transmural ischemia of the right ventricular outflow tract, and reciprocal change to ST-segment depression in lateral leads [2] .…”
