Atrial 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 ...
متن کاملAtypical 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 کاملTypical atrial flutter with atypical flutter wave morphology due to abnormal interatrial conduction.
We report a case of typical counterclockwise atrial flutter (AFL) with conduction block from right to left atrium along the coronary sinus (CS) musculature, confirmed by discontinuous CS activation sequence during pacing near the ostium and differential right atrial pacing. AFL was associated with an atypical flutter wave morphology, due to the detour of the activation wavefront from right to l...

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...
