BACKGROUND Long QT syndrome (LQTS) is characterized by QT prolongation, syncope and sudden death. This study aims to explore the causes, clinical manifestations and therapeutic outcomes of Jervell and Lange-Nielsen syndrome (JLNS), a rare form of LQTS with congenital sensorineural deafness, in Chinese individuals. MATERIALS AND METHODS Three JLNS kindreds… (More)
Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is an inherited heart muscle disease associated with increased risks of sudden death, particularly in young, otherwise healthy, patients. The pathologic features are progressive myocardial atrophy and fibrofatty replacement. Plakophilin-2 (PKP2) is reported as the most common ARVD/C-causing… (More)
OBJECTIVE The purpose of this study was to screen genetic variations in plakophilin-2 (PKP2) gene in patients with arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) and investigate the differences in clinical features between mutation and no-mutation groups. METHODS Thirty unrelated Chinese patients clinically diagnosed with ARVC/D and 50… (More)
We report a case of Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) which illustrates the natural progression of disease in the absence of availability of an implanted cardiac defibrillator (ICD). Electrocardiograms and cardiac imaging show the progress of ARVC and these clinical milestones of disease are presented herein.
OBJECTIVES Genetic testing, a gold standard for long QT syndrome (LQTS) diagnosis, is time-consuming and costly when all the 15 candidate genes are screened. Since genotype-specific ECG patterns are present in most LQT1-3 mutation carriers, we tested the utility of ECG-guided genotyping in a large cohort of Chinese LQTS patients. METHODS AND RESULTS We… (More)
We describe a 45-year-old Asian man with Brugada-type 2 electrocardiogram and probable nocturnal agonal respiration. After genetic screening, drug challenge test and polysomnography examination, we ruled out Brugada syndrome and identified obstructive sleep apnea-hypopnea syndrome. Therefore, obstructive sleep apnea-hypopnea syndrome should be considered as… (More)
Process scheduling is a classical problem in the field of production planning and control; in particular, effective job shop scheduling remains an essential component in today's highly dynamic and agile production environment. This paper presents unified framework for solving generic job shop scheduling problems based on the formulation of a job shop into… (More)
