INTRODUCTION We compared the efficacy and safety of amiodarone and dronedarone in patients with persistent atrial fibrillation (AF). METHODS Five hundred and four amiodarone-naïve patients were randomized to receive dronedarone 400 mg bid (n = 249) or amiodarone 600 mg qd for 28 days then 200 mg qd (n = 255) for at least 6 months. Primary composite… (More)
BACKGROUND Dronedarone is a new multichannel blocker for atrial fibrillation (AF) previously demonstrated to have both rhythm and rate control properties in paroxysmal and persistent AF. The Efficacy and safety of dRonedArone for The cOntrol of ventricular rate during atrial fibrillation (ERATO) trial assessed the efficacy of dronedarone in the control of… (More)
The aim of the study was to determine whether facilitation of reentry by potassium-channel openers is related to dispersion of refractoriness and/or modification of anisotropic properties of ventricular myocardium. The dispersion of ventricular effective refractory period (VERP), longitudinal and transverse ventricular conduction velocities (thetaL and… (More)
We describe in this report the development of chronic left main coronary artery (LMCA) occlusion in a young patient 2 years after an uncomplicated, successful ablation of idiopathic left ventricular tachycardia. This complication appears to be a late consequence of trauma to the LMCA during the procedure rather than an acute or subacute embolic event.
In order to create and evaluate a model sensitive to QT-dependent proarrhythmic effects of drugs, a long QT syndrome was produced in chronically instrumented dogs with bradycardia and hypokalemia. Bradycardia (mean cycle length: 1495 +/- 78 msec) was provided by permanent atrioventricular block and hypokalemia (K+ = 2.6 +/- 0.05 mmol/l) by high doses of… (More)
We present a case of congenital long QT syndrome which developed torsade de pointes during sevoflurane anesthesia for implantation of an internal cardioverter-defibrillator. The diagnosis, implications and treatment are discussed.
Prevalence and prognostic value of conduction disturbances in patients with the Brugada syndrome (BrS) remains poorly known. Electrocardiograms (ECGs) from 325 patients with BrS (47 ± 13 years, 258 men) with spontaneous (n = 143) or drug-induced (n = 182) type 1 ECG were retrospectively reviewed. Two hundred twenty-six patients (70%) were asymptomatic, 73… (More)
Torsades de pointes is the most typical ventricular tachycardia involving QT-interval prolongation. It is a rather unusual but potentially lethal ventricular tachycardia with a distinctive morphology favored by bradycardia, antiarrhythmic drugs and hypokalemia and requires specific treatment. Torsades de pointes has been shown to be related to… (More)
Dobutamine echocardiography (5 and 10 microg/kg/ min) was performed in 40 patients 4 +/- 1 days after acute myocardial infarction reperfused by primary coronary angioplasty. The left ventricle was divided into 11 segments. Reversible myocardial dysfunction was indicated by a decrease in at least 2 grades in the total segmental score. Follow-up… (More)
AIMS SafeR performance versus DDD/automatic mode conversion (DDD/AMC) and DDD with a 250-ms atrioventricular (AV) delay (DDD/LD) modes was assessed toward ventricular pacing (Vp) reduction. METHODS After a 1-month run-in phase, recipients of dual-chamber pacemakers without persistent AV block and persistent atrial fibrillation (AF) were randomly assigned… (More)
