Race and Sex Differences in QRS Interval and Associated Outcome Among Patients with Left Ventricular Systolic Dysfunction [PDF]

, 2017
BACKGROUND: Prolonged QRS duration is associated with increased mortality among heart failure patients, but race or sex differences in QRS duration and associated effect on outcomes are unknown.

Quantum Emitters in Hexagonal Boron Nitride: Principles, Engineering and Applications

Advanced Functional Materials, EarlyView.
Quantum emitters in hexagonal boron nitride have emerged as a promising candidate for quantum information science. This review examines the fundamentals of these quantum emitters, including their level structures, defect engineering, and their possible chemical structures.

Prevalence, Temporal Evolution and Impact on Survival of Ventricular Conduction Blocks in Patients with Acute Coronary Syndrome and Cardiogenic Shock [PDF]

, 2018
Changes in QRS duration and pattern are regarded to reflect severe ischemia in acute coronary syndromes (ACS), and ventricular conduction blocks (VCBs) are recognized high-risk markers in both ACS and acute heart failure.

The main trunk of the left bundle branch is not part of the re-entry circuit of verapamil-sensitive idiopathic left ventricular tachycardia

Journal of Arrhythmia, 2012
We report the case of a 19-year-old man with verapamil-sensitive idiopathic left ventricular tachycardia (ILVT), who had paroxysmal palpitations for 3 years.

Physically motivated projection of the electrocardiogram -- a feasibility study [PDF]

We present PhysECG: a physically motivated projection of the 12 lead electrocardiogram, supported by a deep learning model trained on 21,799 recordings from the PTB-XL database and discuss its feasibility. The method allows to evaluate the epicardial activity (inverse problem of ECG imaging) and, in particular, to distinguish left and right ventricular

Iridium Oxide Inverse Opal Anodes with Tailored Porosity for Efficient PEM Electrolysis

Advanced Functional Materials, EarlyView.
The synthesis of Iridium‐based Inverse Opals (Ir‐IO) is reported as electrocatalyst for Proton exchange membrane water electrolysis (PEM‐WE). Using the developed protocol it produces highly porous materials consisting either of metallic, oxidic Iridium or a combination thereof with large surface areas.

Bundle branch reentry: A rare mechanism of ventricular tachycardia in endomyocardial fibrosis, without ventricular dilation

Indian Heart Journal, 2016
Introduction: Bundle branch reentry as a mechanism of ventricular tachycardia (VT) in endomyocardial fibrosis (EMF) is not described. Case report: A 52-year-old woman with left ventricular (LV) EMF had VT needing cardioversion.
