OBJECTIVE The electrocardiographic (ECG) characteristics and mode of onset of torsade de pointes (TdP) are well described. Less is known about the site of onset of this arrhythmia. This study was conducted to determine if arrhythmias in the long QT syndrome (LQTS) have a predominant site of origin. DESIGN A retrospective analysis of all episodes of LQTS-related arrhythmias recorded in two uni...

Abstract Background and Aims Peritoneal dialysis (PD)-related infections are still associated with an increased risk of morbidity mortality. We describe overview PD peritonitis catheter-related infection (CRI) rates in Malta over a period thirteen years. Method All patients undergoing from 2008 to 2020 were included. Data 2012 was retrospective (shown as mean), whilst data 2013 prospective. ISP...

Background: Atrial arrhythmias (AA) are common in adults with congenital heart disease (ACHD). Although Intra-atrial Reentrant Tachycardia (IART) is well described in ACHD, Atrial Fibrillation (AF) is uncommon, but increasingly recognized. Patients with Transposition of the Great Arteries (TGA) and congenitally corrected-TGA (CC-TGA) have a high burden of AA at a relatively young age. However, ...

This study examined the action tendencies of respect-related emotions in Japanese university students.

Ventricular tachyarrhythmia, in particular ventricular fibrillation, may be partially enabled by an imbalance within the autonomic nervous system. Decreased parasympathetic (or vagal) cardiac regulatory activity may be responsible for the development of conditions that allow ventricular fibrillation to develop and sustain itself. An analysis of R-R intervals immediately prior to episodes of ven...

Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract Episodes of ozone depletion in the lowermost Arctic atmosphere (0–2 km) at polar sunrise have been intensively studied at Alert, Canada, and are thought to result from catalytic reactions involving bromine.
