WebJul 28, 1998 · Clockwise type I atrial flutter was considered present if clockwise activation around the tricuspid annulus was demonstrated and concealed entrainment could be demonstrated from annular pacing sites within the tricuspid valve–eustachian ridge isthmus, with a postpacing interval similar to the flutter cycle length. WebApr 6, 2004 · Surface ECG flutter wave morphology and limited recording intracardiac sites proved insufficient to delineate the precise mechanism of the TI isthmus-dependent …

WebWe hypothesized that phase relationships of atrial flutter waves among different ECG leads could be used to discriminate atrial flutter mechanisms and that vectorcardiography could be used to... WebTypical isthmus‐dependent atrial flutter is a macroreentrant circuit that propagates in a counterclockwise direction around the right atrium, utilizing the cavotricuspid isthmus in an obligate manner. On the surface electrocardiogram, the atrial flutter wave forms a “sawtooth” pattern in the inferior leads (Fig. 1). This pattern is ... WebFeb 11, 2024 · There are inverted flutter waves in II, III + aVF at a rate of 260 bpm.
