Wellens' ECG (sometimes referred to as Wellens syndrome or sign) is an ECG manifestation of proximal left anterior descending stenosis in patients with acute coronary syndrome. It is characterized by symmetrical, often deep (>2 mm), T wave inversions in the anterior precordial leads. A less common variant is biphasic T wave inversions in the same leads. | |||

The De Winter ECG is sometimes seen in myocardial infarction with proximal LAD occlusion. It is rather rare (2% of cases). There is no anterior ST segment elevation. Instead the ST segment shows a 1- to 3-mm upsloping ST-segment depression at the J point in leads V1 to V6 that continues into tall, positive symmetrical T waves. The QRS complexes are usually not widened or only slightly widened, and sometimes there is a loss of precordial R-wave progression. In most patients there is a 1- to 2-mm ST-elevation in lead aVR. <cite>dewinter</cite> | The De Winter ECG is sometimes seen in myocardial infarction with proximal LAD occlusion.
