Biatrial activation in isthmus-dependent atrial flutter.
BACKGROUND The aim of this study was to determine the biatrial activation pattern in isthmus-dependent atrial flutter (AFL) to understand the functional interatrial connections and the activation pattern of the left atrium (LA). METHODS AND RESULTS Biatrial activation was performed, using an electroanatomic mapping system, in 10 patients undergoing right atrial isthmus ablation for counterclo...

متن کاملSurface electrocardiographic characteristics of right and left atrial flutter.
BACKGROUND There is little information about the surface expression of non-cavotricuspid isthmus (CTI)-dependent right atrial (RA) or left atrial (LA) flutter circuits. METHODS AND RESULTS We retrospectively evaluated 32 episodes (in 26 patients) of atypical RA and 22 episodes (in 21 patients) of LA flutter. The surface ECG of 13 patients with lower-loop reentry was similar to that of their p...
متن کاملSeparating non-isthmus- from isthmus-dependent atrial flutter using wavefront variability.
OBJECTIVES The aim of this study was to separate isthmus-dependent atrial flutter (IDAFL) from non-isthmus-dependent atrial flutter (NIDAFL) from the electrocardiogram (ECG) based on functional differences. BACKGROUND The ECG analyses of F-wave shape suboptimally separate NIDAFL from IDAFL. The authors hypothesized that anatomic and functional differences may result in greater wavefront varia...
متن کاملIsthmus Dependent Atrial Flutter Cycle Length Correlates with Right Atrial Cross-Sectional Area
BACKGROUND Right atrial flutter cycle length can prolong in the presence of antiarrhythmic drug therapy. We hypothesized that the cycle length of right atrial isthmus dependent flutter would correlate with right atrial cross-sectional area measurements. METHODS 60 patients who underwent ablation for electrophysiologically proven isthmus dependent right atrial flutter, who were not on Class I ...
