What is Wellens syndrome?
Wellens syndrome describes a pattern of electrocardiographic (ECG) changes, particularly deeply inverted or biphasic T waves in leads V2-V3, that is highly specific for critical, proximal stenosis of the left anterior descending (LAD) coronary artery. It is alternatively known as anterior, descending, T-wave syndrome.
How common is Wellens syndrome?
Wellens and colleagues in 1982 in a subgroup of people with unstable angina, it does not seem to be rare, appearing in 18% of patients in his original study. A subsequent prospective study identified this syndrome in 14% of patients at presentation and 60% of patients within the first 24 hours.
Is Wellens syndrome congenital?
They are congenital coronary anomalies and are discovered in 0.15% of patients undergoing coronary angiography following chest pain or dyspnea.
What is Wellens Type B?
There are two ECG patterns in Wellens’ syndrome: Type A is characterized by deeply symmetrical T-wave inversions in leads V2 and V3, often including leads V1 and V4 and occasionally leads V5 and V6; type B is characterized by biphasic T-waves in leads V2 and V3.
Is Wellens syndrome rare?
Wellens’ syndrome is a rare entity that can also present with T-wave inversions.
Can stress cause inverted T waves?
A study by Whang et al. (2014) showed that depressive and anxious symptoms were associated with abnormalities in T wave inversions.
How do you treat Wellens?
Patients with Wellens syndrome are to be treated as unstable angina. This includes aspirin, nitroglycerin, and pain control, if needed. Patients should be admitted to the hospital where serial cardiac markers and electrocardiograms should be followed.
How is Wellen syndrome treated?
Who discovered Wellens syndrome?
Wellens syndrome was first described in the early 1980s by de Zwaan, Wellens, and colleagues, who identified a subset of patients with unstable angina who had specific precordial T-wave changes and subsequently developed a large anterior wall myocardial infarction (MI).
How is Wellen’s syndrome diagnosed?
The criteria used to diagnose Wellen’s syndrome include symmetric and deeply inverted T waves or biphasic T waves in leads V2 and V3 in a pain-free state, plus isoelectric or minimally elevated (<1 mm) ST segment.
What is normal ECG?
Normal intervals Normal range 120 – 200 ms (3 – 5 small squares on ECG paper). QRS duration (measured from first deflection of QRS complex to end of QRS complex at isoelectric line). Normal range up to 120 ms (3 small squares on ECG paper).
What is Brugada syndrome?
Brugada syndrome is a genetic disorder that can cause a dangerous irregular heartbeat. When this happens, the lower chambers of your heart (ventricles) beat fast and irregularly. This prevents blood from circulating correctly in your body.
