The main criteria for De Winter sign are upsloping ST-segment depression by 0.1 mV at V1-V6 leads and tall symmetrical T waves [2]. Ideally, De Winter's sign-on electrocardiography should be treated as an ST-elevation myocardial infarct (STEMI) equivalent with early cardiac catheter lab activation for percutaneous coronary intervention [2].

De Winter syndrome is a type of acute coronary syndrome, which may be an early ECG pattern in the development of acute ST‐segment elevation myocardial infarction. Therefore, once De Winter syndrome is observed on the ECG, acute coronary syndrome, especially acute anterior descending occlusion should not be ignored.

An electrocardiographic finding suggestive of impending myocardial infarction , the de Winter's pattern (or "de Winter's T-waves") describes an abnormality thought to be indicative of acute occlusion of the proximal left anterior descending coronary artery ( LAD) 2.

The de Winter's electrocardiogram (ECG) pattern signifying proximal left anterior descending (LAD) artery occlusion was first described in 2008. The ECG changes were thought to be static and mechanisms for this were suggested.

Thought to be first described by Dr. Robbert Jan de Winter in 2008 in his letter to the editor to the New England Journal of Medicine, the pattern of peaked T-waves as a sign of myocardial ischemia was actually first noted by Dr. William Dressler in 1947 in a case series of over 27 patients. What de Winter defined was "1- to 3-mm upsloping ST-segment depression at the J point in leads V1 to.

Background The electrocardiogram has a critical role in the diagnosis and risk assessment of patients presenting with chest pain in the emergency ward. Case presentation We present 11 Iranian patients with diagnosis of de Winter referred to our center. Right coronary artery involvement was seen in four cases, left circumflex artery in three cases, proximal left anterior descending artery in.

Background De Winter pattern is associated with acute occlusion in the left anterior descending coronary artery combined with upsloping ST-segment depression at the J point in leads V1 through V6 without ST-segment elevation. The ECG changes in this case were illustrated by an up-sloping ST-segment depression in the V1 to V6 leads, followed by tall and symmetrical T waves. Changes from de.

The De Winter ECG pattern has been reported to indicate acute left anterior descending coronary artery occlusion and is often considered to be an 'ST elevation myocardial infarction (STEMI) equivalent'.

In 2008, de Winter et al described an ECG pattern suggesting that it should be considered an ST‐elevation myocardial infarction (STEMI) equivalent (de Winter, Verouden, Wellens, & Wilde, 2008 ), with the potential to predict critical stenosis or occlusion of the left anterior descending coronary artery (LAD). This ECG pattern typically.

de winter syndrome is a rare pattern that can occur on an electrocardiogram (ECG). 1 It is thought to be related to acute anterior descending artery occlusion. 1 ST-segment elevation myocardial infarction (STEMI) equivalent patterns make the diagnosis of STEMI very challenging. 1 The ECG reveals a de Winter's pattern, which shows a 1 to 3 mm ups.

de Winter syndrome is a rare phenomenon, and it occurs in approximately 2% of patients with myocardial infarction. 2 It has a high predictive value for LAD occlusion. 4 Recent studies suggested that de Winter syndrome may be a transient event before progressing into typical STEMI ECG. 5 The exact electrophysiologic mechanisms involved are not.
