Focal atrial tachycardias arising from the right atrial appendage: electrocardiographic and electrophysiologic characteristics and radiofrequency ablation.
OBJECTIVE To characterize the electrocardiographic and electrophysiological features and frequency of focal atrial tachycardia (AT) originating from the right atrial appendage (RAA). BACKGROUND The RAA has been described as a site of origin of AT, but detailed characterization of these tachycardias is limited. METHODS Ten patients (3.8%) of 261 undergoing radiofrequency ablation (RFA) for f...
متن کاملTopographic distribution of focal left atrial tachycardias defined by electrocardiographic and electrophysiological data.
BACKGROUND Detailed information about the topographic distribution of focal left atrial tachycardias (FLATs) is limited. METHODS AND RESULTS A total of 143 atrial tachycardia (AT) foci were successfully ablated in 140 patients (56 men, mean age 44.6+/-17.9 years). In 36.4% (52/143 ATs), a left atrial (LA) origin of the tachycardia was identified from the site of successful ablation. In 46% (2...
متن کاملP Wave Morphology in Guiding the Ablation Strategy of Focal Atrial Tachycardias and Atrial Flutter
Focal atrial tachycardias arise preferentially from specific locations within the atria. Careful analysis of the P wave can provide useful information about the chamber and likely site of origin within that chamber. Macro-reentrant atrial flutter also tends to occur over a limited number of potential circuits. In this case, the ECG usually gives a guide to the chamber of origin, but unless it s...

متن کاملClinical and electrophysiologic characteristics of left septal atrial tachycardia.
OBJECTIVES It was the purpose of this study to define the electrophysiologic (EP) identity of left septal atrial tachycardia (AT). BACKGROUND The clinical and EP characteristics of this particular type of arrhythmia have not been fully described. METHODS A total of 120 patients with AT underwent invasive EP evaluation. Five patients (two men and three women; mean age 49 +/- 15 years) with l...
