Atrial flutter: from ECG to electroanatomical 3D mapping - PMC
The CARTO electroanatomic 3D mapping system provides important information to completely map and characterize left atrial flutter as well as providing precise localization of the ablation catheter and the graphical presentation of the ablation line.
Three-dimensional Mapping of the Common Atrial Flutter Circuit …
1997年12月2日 · In this study we describe the three-dimensional (3D) activation pattern in the right atrium (RA) during typical atrial flutter by using a new technique of correlative 3D mapping with particular emphasis on superior and septal-medial right atrial activation.
Typical Atrial Flutter Mapping and Ablation - Cardiac …
2022年8月24日 · In addition, the electrophysiological studies in humans had already confirmed the presence of a wide excitable gap through atrial stimulation during atrial flutter (AF) that could reset or terminate the tachycardia.
Mapping and Ablation of Left Atrial Flutters | Circulation
2001年1月1日 · An LA flutter was defined as an atrial arrhythmia with a regular and monomorphic ECG pattern demonstrated by intracardiac mapping to be due to a reentrant circuit in the LA.
Atrial Flutter Mapping and Ablation I - Wiley Online Library
Endocardial mapping has led to a detailed knowledge of reentry mechanisms in atrial flutter. Multipolar and deflecting tip catheters allow recording local electrograms from multiple areas of the right atrium, and from the coronary sinus.
Electrophysiology Study and Ablation of Atrial Flutter
2023年7月8日 · In all cases of atrial flutter, the activation patterns observed during flutter are essential for making an accurate diagnosis. This is particularly important in left atrial patterns, which can be observed in the electrograms of the distal coronary sinus.
Atrial Flutter, Typical and Atypical: A Review - PMC - PubMed …
2017年5月2日 · In 50–80 % of cases flutter interruption can be achieved by atrial pacing above the flutter rate through a transvenous catheter, through epicardial electrodes placed during cardiac surgery or by programming fast atrial rates in …
Atrial flutter mapping and ablation. I. Studying atrial flutter ...
Endocardial mapping has led to a detailed knowledge of reentry mechanisms in atrial flutter. Multipolar and deflecting tip catheters allow recording local electrograms from multiple areas of the right atrium, and from the coronary sinus.
Three-Dimensional (3D) Mapping and Catheter Ablation for …
2023年11月17日 · We present an unusual occurrence of a patient who exhibited two distinct mechanisms of atrial flutter: a clockwise isthmus-dependent flutter and an atypical scar-related flutter around the atriotomy scar.
Abstract 12906: Atypical Atrial Flutter Ablation Utilizing Ultra …
2021年11月8日 · Methods: Twelve patients with atypical atrial flutters and past history of valve surgery, Maze procedure, or persistent atrial fibrillation ablation were identified. We created ultra-high-density 3D maps using 3,000-6,000 points collected with a multipolar PENTARAY catheter and CARTO3 Coherent mapping.
