Atypical right atrial flutter patterns.
BACKGROUND The purpose of our study was to define the incidence and mechanisms of atypical right atrial flutter. METHODS AND RESULTS A total of 28 (8%) of 372 consecutive patients with atrial flutter (AFL) had 36 episodes of sustained atypical right AFL. Among 24 (67%) of 36 episodes of lower loop reentry (LLR), 13 (54%) of 24 episodes had early breakthrough at the lower lateral tricuspid ann...
متن کاملAtypical atrial flutter originating in the right atrial free wall.
BACKGROUND Data from experimental models of atrial flutter indicate that macro-reentrant circuits may be confined by anatomic and functional barriers remote from the tricuspid annulus-eustachian ridge atrial isthmus. Data characterizing the various forms of atypical atrial flutter in humans are limited. METHODS AND RESULTS In 6 of 160 consecutive patients referred for ablation of counterclock...
متن کاملAtrial flutter with atypical presentation
Fifty-five year old lady presented with complaints of recurrent palpitations for last 5 years. She had already undergone 3 previous attempts at ablation at another institution; the details of the procedures were not available. Previous cardiac disease or cardiac surgery was absent. Presenting ECG was consistent with counterclock wise (CCW) atrial flutter (Negative flutter waves in II, III, aVF ...

This is an op under the CC BY-NC-ND license (http://creativecommons.org/licenses/by-nc-nd/4 Introduction Atypical atrial flutter is defined as macroreentrant atrial tachycardia (AT) that does not involve the cavotricuspid isthmus; a variety of reentrant circuits may include reentry around the mitral valve annulus or scar tissue w...
متن کاملNon-contact mapping to guide radiofrequency ablation of atypical right atrial flutter.
OBJECTIVES This study was aimed at evaluating the efficacy of non-contact mapping and ablation of non-incisional atypical right atrial (RA) flutters. BACKGROUND The majority of atypical RA flutters were reported in patients after surgical incision of the RA. METHODS The study group consisted of 15 patients (61 +/- 13 years, 8 males) with atypical atrial flutter (AFL). The RA activation duri...
