Electro-Anatomical Characteristics of Typical Atrial Flutter
Type 1 atrial flutter (AFL) is a macroreentrant tachycardia in the right atrium; the anterior barrier of the common AFL circuit is located at the tricuspid annulus (TA) and the posterior border is functional line of block at the posteromedial (sinus venosa region) right atrium. The upper turnover site of the wave front is mainly located at the anterior to the superior vena cava. Conduction prop...
متن کامل[Typical atrial flutter in the transplanted heart].
Atrial flutter is the most frequent arrhythmia occurring in patients who have undergone orthotopic heart transplantation. We present a representative case of typical atrial flutter with counterclockwise rotation around the tricuspid ring in a female patient who had received an orthotopic heart transplant 13 years before. The arrhythmia pattern seen on the activation map (Figure 1) shows the con...
متن کاملPredictors of atrial fibrillation after ablation of typical atrial flutter.
BACKGROUND The occurrence of atrial fibrillation (AF) after successful ablation of cavotricuspid isthmus-dependent atrial flutter (CTI-AFL) is an important medical event, but predictors of this event are still controversial. OBJECTIVE To determine the incidence of AF and its predictors in patients undergoing ablation of cavotricuspid isthmus-dependent atrial flutter (CTI-AFL). METHODS Fifty...
متن کاملHow to ablate typical atrial flutter.
Typical atrial flutter, as referred to in this article, includes both the counterclockwise and the clockwise form of cavotricuspid isthmus-dependent right atrial flutter. The counterclockwise form is the most common and characterized by a stereotypical surface ECG pattern showing negative sawtooth flutter waves in II, III and aVF at a rate between 200–350 beats.min. This surface ECG morphology ...
متن کاملpredictors of the atrial fibrillation following catheter ablation of typical atrial flutter.
conclusions: catheter ablation of flutter circuit will not prevent later manifestation of af in 16% of the patients undergoing catheter ablation of the typical afl. bmi was the only independent predictor of af following catheter ablation of the typical afl. objectives; to determine long-term incidence and predictors of af after catheter ablation of typical afl. material and methods: between mar...
