Dispersion of atrial repolarization in patients with paroxysmal atrial fibrillation.
UNLABELLED To study the role of the dispersion of atrial repolarization (DAR) in the genesis of atrial fibrillation (AF), monophasic action potentials (MAP) were recorded simultaneously from a catheter at the high lateral right atrium (HLRA) and a catheter moving around the high, middle and low lateral right atrium (RA) the high, anterior and posterior septal RA and the RA appendage in 15 patie...
متن کاملCanine model of paroxysmal atrial fibrillation and paroxysmal atrial tachycardia.
Both autonomic nerve activity and electrical remodeling are important in atrial arrhythmogenesis. Therefore, dogs with sympathetic hyperinnervation, myocardial infarction (MI), and complete atrioventricular block (CAVB) may have a high incidence of atrial arrhythmias. We studied eight dogs (experimental group) with MI, CAVB, and sympathetic hyperinnervation induced either by nerve growth factor...
متن کاملSignal-averaged P wave in patients with paroxysmal atrial fibrillation.
The theoretical and experimental rational of atrial signal-averaged ECG in patients with AF is delay in the intra-atrial and interatrial conduction. Similar to the ventricular signal-averaged ECG, the atrial signal-averaged ECG is an averaging of a high number of consecutive P waves that match the template created earlier P wave triggering is preferred over QRS triggering because of more accura...
متن کاملElectromechanical Abnormalities in Patients with Paroxysmal Atrial Fibrillation
Background: The loss of effective atrial contraction is associated with an increased thromboembolic risk. Aim: To study the electromechanical coupling of the atria in patients with paroxysmal atrial fibrillation (time of occurrence of the episodes <48 hours) using pulsed-wave tissue Doppler imaging. Materials and methods: The study included 51 patients (26 men, 25 women; mean age 59.84±1.60 yea...
متن کاملCryoballoon ablation in young patients with lone paroxysmal atrial fibrillation.
INTRODUCTION AND OBJECTIVES Long-term efficacy following cryoballoon ablation of lone paroxysmal atrial fibrillation remains unknown. We describe long-term follow-up results of the single cryoballoon ablation procedure. METHODS Pulmonary vein isolation was performed in 103 patients (72 male; median age 52 years) with symptomatic lone paroxysmal atrial fibrillation. The end-point of this obser...
