Wellens' syndrome is characterized by T-wave changes in electrocardiogram (EKG) during pain-free period in a patient with intermittent angina chest pain. It carries significant diagnostic and prognostic value because this syndrome represents a pre-infarction stage of coronary artery disease involving proximal left anterior descending (LAD) artery, which can subsequently lead to extensive anterior myocardial infarctions (MIs) and even death without coronary angioplasty. Therefore, it is crucial for every physician to recognize EKG features of Wellens' syndrome in order to take appropriate immediate intervention to reduce mortality and morbidity for MI...

A 64year old man presented with atypical chest pain of 6h duration. Physical examination showed tachycardia and an irregularly irregular pulse. Initial EKG showed atrial fibrillation with rapid ventricular rate. Intravenous Diltiazem was administered following which there was resolution of atrial fibrillation as well as his chest pain. Troponin T and CPK-MB were minimally elevated at 0.05ng/ml (0.0-0.03ng/ml) and 8.6ng/ml (0.0-7.0ng/ml) respectively. A repeat EKG obtained after symptom resolution showed biphasic T wave inversions in V2 and V3 which prompted an emergent coronary angiogram that revealed 90% occlusion of the proximal LAD...

BACKGROUND: A proband of Brugada syndrome (BrS) is the first patient diagnosed in a family. There are no data regarding this specific, high-risk population. OBJECTIVES: This study sought to investigate the Brugada probands diagnosed from 1986 through the next 28 years. METHODS: We included 447 probands belonging to families with a diagnostic type 1 electrocardiogram Brugada pattern. The database was divided into 2 periods: the first period identified patients who were part of the initial cohort that became the consensus document on BrS in 2002 (early group); the second period reflected patients first diagnosed from 2003 to January 2014 (latter group)...

BACKGROUND: Reperfusion after coronary occlusion (myocardial infarction, MI), as in Wellens' syndrome, is often represented on ECG as T-wave inversion in the leads overlying the affected myocardial wall(s). As an extension of this logic, reperfusion of the posterior wall should manifest on right precordial leads (which are opposite the posterior wall) as enlarged T-waves. OBJECTIVE: We sought to determine whether T-wave amplitude (TWa) in leads V2 and V3 after reperfusion in posterior MI (PMI) is greater than in patients without PMI...

The case is a 52-year-old male admitted to cardiology department with chest tightness. Admission ECG showed nontypical T-wave changes in V2-V4 leads in pain peroids, and increasing severe narrowing of proximal LAD. Cardiac enzymes were abnormal. Emergency coronary angiography showed severe stenosis (99%) in proximal LAD.

Wellens' Syndrome is a pattern of electrocardiographic T-wave changes associated with critical, proximal left anterior descending (LAD) artery stenosis. Diagnostic criteria of Wellens' Syndrome are history of chest pain, little or no cardiac enzyme elevation, little or no ST-segment elevation, no loss of precordial R waves, no pathologic precordial Q waves and typical T-wave changes. Urgent cardiac catheterization is vital to prevent myocardial necrosis. Here we are presenting two cases with Wellens' Syndrome who had been sent for catheterization before marked myocardial infarction developed...

INTRODUCTION: Wellens Syndrome (WS) is a condition characterized by typical changes in ECG, which are biphasic T-wave inversions (less common) or symmetric and deeply inverted T waves (including 75%) in lead V2-V3 chest derivations. WS is considered important because it has not only diagnostic value but also prognostic value. CASE REPORT: A 52-year-old male patient without cardiovascular disease or risk factors was admitted to the emergency department (ED) suffering with chest pain and syncope, just after having been involved in a discussion at work...

AIM: The aim of our study is to compare two approaches of implantable cardiac defibrillator (ICD) implantation, conventional (supra/subpectoral) and subcostal in young adults in terms of procedural complications and adverse events encountered during follow-up. METHODS AND RESULTS: From January 2007 to December 2013, all patients under the age of 50 years who received an ICD in our centre were included in this study. Patient's hospital records were analysed for procedural complications and adverse events during follow-up until December 2014...

BACKGROUND: Among Brugada syndrome patients, asymptomatic individuals are considered to be at the lowest risk. Nevertheless, arrhythmic events and sudden cardiac death are not negligible. Literature focused on this specific group of patients is sparse. The purpose of this study is to investigate the clinical characteristics, management, and long-term prognosis of asymptomatic Brugada syndrome patients. METHODS AND RESULTS: Patients presenting with spontaneous or drug-induced Brugada type I ECG and no symptoms at our institution were considered eligible...

REVIEW
Shams Y-Hassan
Reversible electrocardiographic (ECG) repolarization changes including T-wave inversions (TWI), large upright peaked T-waves (LUPTW) and prolongation of the corrected QT interval (P-QTc) have been reported in association with myriads of acute cardiac and non-cardiac diseases. Through the last 70 years, the TWIs have been described under different terms as; cerebral, giant, global, canyon, Wellens or coronary and cardiac memory T waves. During the last 15 years, the reversible TWI and LUPTW in association with P-QTc have been described as characteristic ECG features in takotsubo syndrome (TS), which also may be triggered by the same aforementioned acute cardiac and non-cardiac disease entities...

We describe a case of a 42-year-old man, with a previous episode of angina and a normal ECG and serum cardiac markers, and a two months later finding of biphasic T wave in leads V2-V3 and deeply inverted T wave in V4-V5 at a asymptomatic occupational evaluation. This is a typical ECG pattern of Wellens' syndrome. A subsequent coronary angiography showed a critical stenosis of proximal left anterior descendent. We underline the careful value of prolonged observation in chest pain unit and repetitive ECG evaluation also during pain-free period after an angina episode, to exclude an earlier T wave pseudonormalization...

BACKGROUND: The prognostic value of electrophysiological investigations in individuals with Brugada syndrome remains controversial. Different groups have published contradictory data. Long-term follow-up is needed to clarify this issue. METHODS AND RESULTS: Patients presenting with spontaneous or drug-induced Brugada type I ECG and in whom programmed electric stimulation was performed at our institution were considered eligible for this study. A total of 403 consecutive patients (235 males, 58...

Electrocardiographic characteristics of Wellens syndrome (WS) consist of deeply inverted T waves or biphasic T waves in anterior precordial leads. Studies have shown that patients with WS have critical stenosis or complete obstruction of the proximal left anterior descending coronary artery (LAD) and high risk for the development of extensive anterior myocardial infarction. Here, we reported a case presenting with WS and with a small plaque in the proximal LAD and slow flow in the LAD other than significant stenosis of the proximal LAD detected by coronary angiography...
