INTRODUCTION Asymptomatic atrial fibrillation (AF) can expose patients to the risk of stroke. The primary objective of this study was to assess the incidence of thromboembolic events in relationship with CHADS(2) (congestive heart failure, hypertension, age >or=75 years, diabetes mellitus, and prior stroke, or transient ischemic attack) score and AF(More)
BACKGROUND In-hospital administration of flecainide and propafenone in a single oral loading dose has been shown to be effective and superior to placebo in terminating atrial fibrillation. We evaluated the feasibility and the safety of self-administered oral loading of flecainide and propafenone in terminating atrial fibrillation of recent onset outside the(More)
BACKGROUND Because of its episodic behavior, the correlation of spontaneous syncope with an abnormal finding can be considered a reference standard. METHODS AND RESULTS We inserted an implantable loop recorder in 111 patients with syncope, absence of significant structural heart disease, and a normal ECG; tilt-testing was negative in 82 (isolated syncope)(More)
Atrial fibrillation (AF) is associated with impaired functional capacity and quality of life and significant morbidity and mortality. The current management approach fails to maintain stable sinus rhythm (SR) in the majority of patients. For many years, guidelines have recommended antiarrhythmic treatment of a first AF episode only if the AF is poorly(More)
BACKGROUND New atrial pacing techniques and overdrive pacing algorithms have been introduced to prevent atrial fibrillation. This study was designed to test the hypotheses that (1) interatrial septum pacing (IASP) at the triangle of Koch would be more effective than right atrial appendage pacing (RAAP) in preventing paroxysmal atrial fibrillation (PAF) in(More)
OBJECTIVES The aim of our study was to evaluate arterial embolism (AE) occurrence rates and predictors in patients suffering from bradycardia and wearing a pacemaker with antitachycardia pacing therapies. BACKGROUND Atrial fibrillation (AF) is associated with a high incidence of AE. METHODS A total of 725 patients (360 men, age 71 +/- 11 years) were(More)
BACKGROUND In patients with syncope and structural heart disease, syncope is suspected to be attributable to a primary cardiac arrhythmia, but little is known of its mechanism when electrophysiologic study is unremarkable. METHODS AND RESULTS We applied an implantable loop recorder in 35 patients with overt heart disease at risk of ventricular arrhythmia,(More)
BACKGROUND The effectiveness of oral propafenone in converting recent-onset atrial fibrillation to sinus rhythm has been established by controlled trials. However, it is not clear whether the effectiveness of propafenone is affected by the presence or absence of underlying heart disease. OBJECTIVES To investigate the safety and effectiveness of oral(More)
INTRODUCTION Right atrial linear lesions (RALL), either alone or in combination with antiarrhythmic drug therapy, may modify the substrate for maintenance of atrial fibrillation (AF). The aim of this prospective randomized study was to determine whether RALL provides additional benefit to right atrial appendage pacing (RAAP) and/or interatrial septum pacing(More)
OBJECTIVE To evaluate the 2-year clinical improvement after 'Ablate and Pace' therapy and to identify the variables able to influence the efficacy of this therapy in patients with permanent atrial fibrillation (AF). Design Prospective multicentre observational study. Setting Cardiology departments of 19 general hospitals in Italy, Spain and Greece. (More)
