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...

There is a sinus P wave in front of each QRS, and the rate is 122 beats/min. The QRS voltage is large and meets many criteria for left ventricular hypertrophy: RI > 13 mm (1.3 mV); RaVF > 19 mm; SaVR > 14 mm; SV1 > 24 mm; SV2 > 30 mm; RV6 > 26 mm; RV6 > RV5; SV1 + RV5 or RV6 > 35 mm; SV2 + RV5 or RV6 > 45 mm; RaVL + SV3 > 20 mm in a woman.1 In addition, there are two non-voltage criteria for LVH: QRS duration = 0.11 s and typical repolarization changes: J-point depression with a downsloping ST segment into an inverted T wave and a more rapid upslope back to the baseline...

BACKGROUND: The subcutaneous implantable cardioverter defibrillator (S-ICD) provides an attractive option for patients with congenital heart disease (CHD) in whom a transvenous defibrillator is contraindicated. Given the unusual cardiac anatomy and repolarization strain, the surface electrocardiogram (ECG) is frequently abnormal, potentially increasing the screen failure rate. METHODS AND RESULTS: We prospectively screened 100 adult CHD patients regardless of the presence of clinical indication for ICD utilizing a standard left sternal lead placement, as well as a right parasternal position...

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...

BACKGROUND: ST-T wave (STTW) abnormalities have been described in 20-40% of normal newborns. We sought to describe the associations of these Electrocardiogram (ECG) abnormalities to perinatal course and congenital heart disease (CHD). METHODS: A retrospective chart review was performed on all neonatal ECGs between January 2008 and March 2013 identified from electronic medical records. Electronic medical records were reviewed for perinatal course and maternal medical conditions...

BACKGROUND: Sex differences in clinical presentation and outcomes of hereditary arrhythmias are commonly reported. We aimed to compare clinical presentation and outcomes in men and women with arrhythmogenic right ventricular cardiomyopathy (ARVC) enrolled in the North American ARVC Registry. METHODS: A total of 125 ARVC probands (55 females, mean age 38 ± 12; 70 males, mean age 41 ± 15) diagnosed, as either "affected" or "borderline" were included. Baseline clinical characteristics and time-dependent outcomes including syncope, ventricular tachycardia (VT), fast VT (>240 bpm), ventricular fibrillation (VF), and death were compared between males and females...

Alkali-doped fullerides A 3C60 (A = K, Rb, Cs) are surprising materials where conventional phonon-mediated superconductivity and unconventional Mott physics meet, leading to a remarkable phase diagram as a function of volume per C60 molecule. We address these materials with a state-of-the-art calculation, where we construct a realistic low-energy model from first principles without using a priori information other than the crystal structure and solve it with an accurate many-body theory. Remarkably, our scheme comprehensively reproduces the experimental phase diagram including the low-spin Mott-insulating phase next to the superconducting phase...

OBJECTIVES: Treatment guidelines for acute pulmonary embolism (PE) recommend risk stratifying patients to assess PE severity, as those at higher risk should be considered for therapy in addition to standard anticoagulation to prevent right ventricular (RV) failure, which can cause hemodynamic collapse. The hypothesis was that 12-lead electrocardiography (ECG) can aid in this determination. The objective of this study was to measure the prognostic value of specific ECG findings (the Daniel score, which includes heart rate > 100 beats/min, presence of the S1Q3T3 pattern, incomplete and complete right bundle branch block [RBBB], and T-wave inversion in leads V1-V4, plus ST elevation in lead aVR and atrial fibrillation suggestive of RV strain from acute pulmonary hypertension), in patients with acute PE...
