BACKGROUND: Wellens syndrome is a pattern of electrocardiographic (ECG) changes in the context of unstable angina characterized with deep inverted T-waves or biphasic T-waves in the precordial leads. These specific ECG changes are highly suggestive of stenosis in the left anterior descending artery (LAD), which can result in acute myocardial infarction, left ventricular dysfunction, or death. Human immunodeficiency virus (HIV) infection is known as an independent risk factor for the cardiovascular disease...

BACKGROUND: Arrhythmogenic right ventricular dysplasia/cardiomyopathy is characterized by ventricular arrhythmias and sudden cardiac death. Once the diagnosis is established, risk stratification to determine whether implantable cardioverter-defibrillator (ICD) placement is warranted is critical. METHODS AND RESULTS: The cohort included 312 patients (163 men, age at presentation 33.6±13.9 years) with definite arrhythmogenic right ventricular dysplasia/cardiomyopathy who received an ICD...

Some patients with unstable angina and critical stenosis of the left anterior descending coronary artery (LAD) present with Wellens syndrome (WS), i.e., inverted or biphasic T-waves in the anterior precordial leads. We assessed clinical, angiographic, electro- and echocardiographic characteristic of patients with WS. In this retrospective study, clinical, angiographic, electro- and echocardiographic characteristic of 35 patients with WS were compared to 57 patients with critical LAD stenosis and normal resting electrocardiogram (ECG), and 45 subjects with normal coronary angiogram...

BACKGROUND Electrocardiographic presentations of left ventricle aneurysms are diverse; however, a persistent ST segment elevation post myocardial infarction is most commonly reported. CASE REPORT The authors present a case of a 67-year-old man who presented to the emergency department after three days of chest pain and was found to have an acute myocardial infarction with an incidental finding of a left ventricular aneurysm. His surface electrocardiogram, however, demonstrated only inverted T waves in the precordial leads...

Wellens' syndrome consists of a history suggestive of an acute coronary syndrome and biphasic or deeply inverted T waves in ECG leads V2-V3. A shortcut review was carried out to establish whether this ECG pattern identifies patients with a critical left anterior descending artery stenosis. Six relevant papers were found. The clinical bottom line is that biphasic T-wave inversion in lead V2-V3 should alert the clinician to a probable critical stenosis of the left anterior descending artery.

Coved-type ST-segment elevation in the right precordial leads are the characteristics of Brugada syndrome, an inherited arrhythmogenic ion channel disease, which could lead to ventricular arrhythmia and sudden death. Hypokalemia alone may induce Type 1 Brugada pattern electrocardiogram (EKG), and the association has rarely been reported. We describe a patient with hypokalemia 2.9 mmol/L and the appearance of new right bundle branch block pattern with coved ST-segment elevations with inverted T wave in leads V1-V2...

A 67-year-old man was admitted to our hospital after episodes of syncope preceded by malaise and diffuse neck and chest discomfort. No family history of cardiac disease was reported. Laboratory workup was within normal limits, including D-dimers, serum troponin I and arterial blood gases. The electrocardiogram showed sinus rhythm with T-wave inversion in leads V1 to V3. Computed tomography angiography to investigate pulmonary embolism showed no abnormal findings. Transthoracic echocardiography (TTE) displayed massive enlargement of the right ventricle with intact interatrial septum and no pulmonary hypertension...

BACKGROUND: Takotsubo cardiomyopathy (TCM) is caused by excessive physical and mental stress, and sometimes causes potentially fatal arrhythmias such as torsades de pointes. This study characterized the features of TCM due to aneurysmal subarachnoid hemorrhage, particularly the delayed normalization of electrocardiograms compared with that of transthoracic echocardiograms. METHODS: Ten patients with TCM were selected from the 450 patients with subarachnoid hemorrhage treated in our hospital between January 2007 and November 2015...

We experimentally study 2p photoionization of neon dimers (Ne_{2}) at a photon energy of hν=36.56  eV. By postselection of ionization events which lead to a dissociation into Ne^{+}+Ne we obtain the photoelectron angular emission distribution in the molecular frame. This distribution is symmetric with respect to the direction of the charged vs neutral fragment. It shows an inverted Cohen-Fano double slit interference pattern of two spherical waves emitted coherently but with opposite phases from the two atoms of the dimer...

We report the case of an 86-year-old man found at home with acute chest pain and dyspnea. He presented some episodes of left chest pain combined with dyspnea. The physical examination revealed crackling sounds on the bases of the lungs without other anomalies. Electrocardiograms revealed a transient and complete right bundle branch block with inverted T waves in leads V1, V2, and V3. He was diagnosed with a proximal bilateral acute pulmonary embolism without acute cor pulmonale. We describe a case of a transient bundle branch block, without tachycardia or acute cor pulmonale, revealing a pulmonary embolism...

CLINICAL INTRODUCTION: A 75-year-old patient with hypertension and severe aortic stenosis underwent elective coronary angiography that showed mild non-obstructive disease in the mid left anterior descending artery (LAD). A left ventriculogram, however, demonstrated segmental systolic dysfunction with dilated akinetic apex (figure 1A, see online supplementary video 1). There was no history of prior myocardial infarction and the patient had not experienced any chest pain recently. A 12-lead ECG showed widespread deep symmetrical inverted T-waves with the exception of leads I, aVL and V1 (see online supplementary figure S1)...

A 70-year-old female underwent an emergency replacement of the ascending aorta for acute aortic dissection. We used surgical adhesive BioGlue and teflon felt strips to reinforce the dissected aortic wall. On the 5th post operative day, electrocardiogram showed ischemic inverted T wave and the serum creatine phosphokinase level elevated without any symptoms such as chest pain or low blood pressure. By coronary angiography, severe stenosis was detected of the left descending coronary artery, and percutaneous coronary intervention was performed...
