AIMS Assessment of ECG-features as predictors of sudden death in adults with hypertrophic cardiomyopathy (HCM). METHODS AND RESULTS ECG-amplitude sums were measured in 44 normals, 34 athletes, a hospital-cohort of 87 HCM-patients, and 29 HCM-patients with sudden death or cardiac arrest (HCM-CA). HCM-patients with sudden death or cardiac arrest had(More)
OBJECTIVES The purpose of this study was to analyze the velocities across the coronary sinus ostium (cross-CSo) and within the coronary sinus (intra-CS) in patients with and without paroxysmal atrial (AF) fibrillation and to estimate the interatrial conduction deterioration area in AF patients. BACKGROUND Interatrial conduction delay in AF patients has(More)
OBJECTIVES To investigate the total dispersion of ventricular repolarization of the epi- and endocardium. DESIGN Monophasic action potentials (MAP) were recorded from 211+/-54 (151-353) left and right ventricular epi- and endocardial sites during atrial pacing in 10 pigs using the CARTO system. The activation time (AT), MAP duration (MAPd) and end of(More)
Inter-atrial conduction delay in patients with atrial fibrillation (AF) has been reported. However, the area of this conduction delay has not been well identified. The activation time and conduction velocity over the right atrial endocardium were evaluated during sinus rhythm using the CARTO mapping technique in 6 patients with paroxysmal AF (AF group) and(More)
BACKGROUND Local ventricular refractoriness and its dispersion during ventricular fibrillation (VF) have not been well evaluated, due to methodological difficulties. METHODS In this study, a non-invasive method was used in evaluation of local ventricular refractoriness and its dispersion during induced VF in 11 patients with VF and/or polymorphic(More)
OBJECTIVES Comparisons between remote magnetic (RMN) and manual catheter navigation for atrial fibrillation (AF) ablation have earlier been reported with controversial results. However, these reports were based on earlier generations of the RMN system. DESIGN To evaluate the outcomes of the most current RMN system for AF ablation in a larger patient(More)

The trigger mechanism of paroxysmal atrial fibrillation is usually an atrial ectopic beat originating in the muscular sleeves of the pulmonary veins. These and other origins of the trigger mechanisms can be explored with electroanatomical mapping technique. Once identified, the trigger mechanism may be abolished by using the catheter ablation technique to(More)
