Thein Swe, Muhammad Hassan Dogar
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 (SAH), particularly the delayed normalization of electrocardiograms compared to that of transthoracic echocardiograms. METHODS: Ten patients with TCM were selected from the 450 SAH patients 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...

BACKGROUND: Athletes' health is an important issue and for promoting it, pre-participation examination (PPE) is widely performed by responsible bodies around the world. OBJECTIVES: This study was to determine prevalence of cardiovascular disorders among athletes participating in the Asian games and answering the question whether the electrocardiogram (ECG) is a necessary part of pre-participation examination (PPE) for prevention of sudden cardiac death. MATERIALS AND METHODS: All athletes participated at Asian games came to sports medicine federation for a PPE including a comprehensive questionnaire, physical examination and ECG...

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...

The objective of this study was to investigate the prognostic significance of 12-lead electrocardiogram (ECG) patterns in a large multicenter cohort of patients with hypertrophic cardiomyopathy; 1,004 consecutive patients with hypertrophic cardiomyopathy and a recorded standard ECG (64% men, mean age 50 ± 16 years) were evaluated at 4 Italian centers. The study end points were sudden cardiac death (SCD) or surrogates, including appropriate implanted cardiac defibrillator discharge and resuscitated cardiac arrest and major cardiovascular events (including SCD or surrogates and death due to heart failure, cardioembolic stroke, or heart transplantation)...

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...

AIM: The present study has been conducted to evaluate the variation in electrocardiogram (ECG) parameters among different trained breeds of dogs (viz. Labrador, German Shepherd, and Golden Retriever) used for security reasons. MATERIALS AND METHODS: The ECG was recorded by single channel ECG at a paper speed of 25 mm/s and calibration of 10 mm=1 mV. The recordings were taken from all the standard bipolar limb leads (Lead-I, II, and III) and unipolar augmented limb leads (Lead-aVR, aVL, and aVF)...

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...
