Spontaneous Demonstration Of Counterclockwise Right Atrial Activation Following Successful Isthmus Ablation
نویسندگان
چکیده
We describe an uncommon case of typical flutter with symptomatic sinus node dysfunction, in which a permanent junctional rhythm developed following ablation of the cavo-tricuspid isthmus. This rhythm activated the right atrium in counter clockwise manner thus providing spontaneous proof of unidirectional isthmus block, a phenomenon that is usually demonstrated by proximal coronary sinus pacing.

How 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 کاملIsoproterenol to evaluate resumption of conduction after right atrial isthmus ablation in type I atrial flutter.
BACKGROUND After radiofrequency (RF) ablation of atrial flutter (AFL), the demonstration of bidirectional isthmus conduction (BIC) block is considered the hallmark of a successful procedure. The purpose of our study was to test the persistence of BIC block after isoproterenol administration and to evaluate the importance of this finding with regard to AFL recurrences. METHODS AND RESULTS RF a...
متن کاملBiatrial 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...

OBJECTIVE To describe the electrocardiographic and electrophysiological findings of new atrial flutter developing in patients taking class IC antiarrhythmic drugs for recurrent atrial fibrillation, and to report the long term results of right atrial isthmus ablation in relation to the ECG pattern of spontaneous atrial flutter. DESIGN Retrospective analysis. SETTING Tertiary care academic ho...
متن کاملUsefulness of unipolar electrograms to detect isthmus block after radiofrequency ablation of typical atrial flutter.
BACKGROUND RS morphology of the unipolar electrogram is associated with propagation of the wave front through the exploring electrode, whereas positive uniphasic (R) unipolar electrograms are characteristic of the end of activation. METHODS AND RESULTS Unipolar electrograms were recorded in 45 consecutive patients with atrial flutter who were undergoing radiofrequency ablation (RFA). Bidirect...
