Context-oriented programming (COP) introduces dedicated abstractions for the modularization and dynamic composition of crosscutting context-specific functionality. While existing COP languages offer constructs for control-flow specific composition, they do not yet consider the explicit representation of event-specific context-dependent behavior, for which(More)
BACKGROUND The posterior right atrial transverse conduction capability during typical atrial flutter (AFL) is well known, but its relationship to the anatomical characteristics remains controversial. METHODS AND RESULTS Thirty-four AFL and 16 controls underwent intracardiac echocardiography after placement of a 20-polar catheter at the posterior block(More)
The cavotricuspid isthmus (CTI) is crucial in the ablation of typical atrial flutter (AFL), and consequently the CTI anatomy and/or its relation to resistant ablation cases have been widely described in human angiographic studies. Intracardiac echocardiography (ICE) has been shown to be a useful tool for determining detailed anatomical information. Thus,(More)
INTRODUCTION The activation sequence in typical atrial flutter (AFL) around the tricuspid annulus is well described. However, activation of the remainder of the right atrium (RA) is not well defined. Previous studies have shown a linear block at the crista terminalis (CT) during AFL. The aim of this study was to evaluate the relationship between the(More)
BACKGROUND The study examined the electrocardiographic and electrophysiologic characteristics in relation to programmed ventricular stimulation (PVS)-induced ventricular fibrillation (VF) in patients with Brugada syndrome. METHODS AND RESULTS Thirty-four patients with a Brugada-type electrocardiogram (ECG) were enrolled. Twelve patients had a type 1 ECG,(More)
BACKGROUND It remains unknown why atrial flutter (AFL) occurs as either a chronic or paroxysmal arrhythmia. PURPOSE The aim of the study was to compare intracardiac echocardiographic (ICE) images of the crista terminalis (CT) and transverse conduction properties of the CT between chronic and paroxysmal forms of common AFL. METHODS Chronic AFL (n = 7)(More)
BACKGROUND High-speed rotational coronary venous (CV) angiography (RCVA) permits dynamic, multi-angle visualization of the CV anatomy. METHODS AND RESULTS RCVA uses a rapid isocentric rotation over a 108 degrees arc, right anterior oblique (RAO) 54 degrees to left anterior oblique (LAO) 54 degrees, in 4 s. Three-dimensional models of the venous tree were(More)
Beraprost sodium (BPS, an analogue of prostacyclin) and telmisartan (TS, an angiotensin receptor blocker) have been reported to have a preventive effect on arterial stiffness in patients with cardiovascular diseases. The purpose of this study was to estimate the effects of a combined therapy using BPS and TS on arterial pulse wave velocity (PWV) values in(More)
