What does Wellens syndrome mean?

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.

What is Wellens criteria?

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.

Is Wellens a stemi?

Understanding T wave changes The following sequence of events is thought to occur in patients with Wellens syndrome: A sudden complete occlusion of the LAD causes a transient anterior STEMI, causing chest pain & diaphoresis.

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 ACS a Wellens syndrome?

As a well-known high-risk ACS, Wellens’ syndrome, first described by de Zwaan and Wellens in 1982 [4], is the characteristic ST-T segment change in the precordial leads, indicating a critical stenosis high in the left anterior descending arterial (LAD).

Is LBBB a STEMI?

In the recent version of the guidelines, LBBB is no longer an automatic STEMI equivalent.

How does takotsubo syndrome present?

The main symptoms are sudden chest pain, shortness of breath or fainting – usually after feeling severe stress. These symptoms are similar to those of a heart attack, so if you experience these symptoms, call an ambulance straight away (dial 000 if in Australia).

Is Wellens syndrome rare?

Wellens’ syndrome is a rare entity that can also present with T-wave inversions. It comes in two flavors.

How is Wellen syndrome treated?

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.

Is Wellens syndrome stemi?

What is Brugada syndrome?

Brugada syndrome is a rare but serious condition that affects the way electrical signals pass through the heart. It can cause the heart to beat dangerously fast. These unusually fast heartbeats – known as an arrhythmia – can sometimes be life threatening.

What is Dressler’s syndrome?

Dressler syndrome is a type of inflammation of the sac surrounding the heart (pericarditis). Dressler syndrome is believed to be an immune system response after damage to heart tissue or to the sac surrounding the heart (pericardium).

How is Wellens syndrome diagnosed?

Can stress cause inverted T waves?

Whether it is due to short-term test nervousness or a chronic condition, anxiety may be associated with certain ECG abnormalities, including T-wave inversion.

When should you suspect posterior MI?

ST elevation in the posterior leads of a posterior ECG (leads V7-V9). Suspicion for a posterior MI must remain high, especially if inferior ST segment elevation is also present. ST segment elevation in the inferior leads (II, III and aVF) if an inferior MI is also present.

Does Covid cause Brugada?

12, 13, 14 The severe inflammatory response to COVID-19 results in a febrile illness in the vast majority of patients. 15 As shown in our case, COVID-19-induced fever led to symptomatic Brugada syndrome.

In what age does Brugada syndrome start?

Brugada syndrome may affect individuals of any age, but symptoms most often occur in middle-aged men around the age of 40. The disorder was first described in the medical literature in 1992.

Is Dressler syndrome serious?

Rarely, Dressler syndrome can cause more-serious complications, including: Cardiac tamponade. Inflammation of the pericardium can cause fluids to accumulate in the sac (pericardial effusion). The fluid can put pressure on the heart, forcing it to work harder and reducing its ability to pump blood efficiently.

Is Dressler’s syndrome fatal?

Is Dressler’s syndrome fatal? Rarely, Dressler’s syndrome symptoms can be life-threatening. It’s important to seek medical treatment if you experience chest pain and have trouble breathing, especially if you’ve recently been in the hospital for heart issues.

Is T-wave inversion serious?

Conclusions— T-wave inversions in right precordial leads are relatively rare in the general population, and are not associated with adverse outcome. Increased mortality risk associated with inverted T waves in other leads may reflect the presence of an underlying structural heart disease.

How serious is T-wave abnormality?

Abnormalities of the T wave are associated with a broad differential diagnosis and can be associated with life-threatening disease or provide clues to an otherwise obscure illness.

How is posterior MI diagnosed?

Posterior infarction is diagnosed based on the presence of ST segment elevation >0.5mm in leads V7-9. Note that there is also some inferior STE in leads III and aVF (but no Q wave formation) suggesting early inferior involvement.

What symptoms are common in a posterior myocardial infarction?

Posterior myocardial infarction, like other types of myocardial infarction, classically presents with chest pain….Factors that increase the probability of ACS include:

• associated with nausea or vomiting.
• associated with diaphoresis.
• is worse with exertion or strong emotion.
• Chest pain that radiates to the arms or jaw.

How long can you live with Brugada syndrome?

Life expectancy for Brugada syndrome depends on early diagnosis and treatment. Brugada syndrome may be a major cause of sudden cardiac death in men under 40. People with Brugada syndrome on average die between the ages of 26 to 56 years, with an average age of 40 years.

Can you live a long life with Brugada?

Brugada syndrome may be a major cause of sudden cardiac death in men under 40. People with Brugada syndrome on average die between the ages of 26 to 56 years, with an average age of 40 years. If treated appropriately, patients can have a normal lifespan.

Is Dressler’s syndrome curable?

The outlook for Dressler syndrome is generally favorable. But it does depend on how quickly the condition is diagnosed and treated. Though rare, long-term follow-up is recommended because of the risk of complications, like cardiac tamponade, which can be fatal.
