Background Atrial flutter with 1:1 conduction often presents with broad complex tachycardia (BCT), commonly misdiagnosed as ventricular tachycardia (VT). The utility of standard ECG algorithms for classification of BCT has not been evaluated in this subgroup. Methods 25 patients had confirmed atrial...
The differential diagnosis included typical flutter, atypical flutter, and focal atrial tachycardias with 2:1 conduction block. P waves were positive in V1 and across all precordial leads (absent precordial transition). This favors atypical flutter originating from the left atrium over t...
mapping was performed which confirmed the right isthmic block and documented the left origin of the flutter, showing conduction gaps in the ostia of the pulmonary veins and in the previous anterior ablation line between the mitral annulus and the right superior pulmonary vein (RSPV) (Fig 2,3)....
The results from the progressive- and standing-wave tests indicate that for each of the wave-loading regimes, there exists a critical cyclic stress ratio below which liquefaction does not occur. The critical value for the progressive-wave-loading series was found to be considerably smaller than ...
Background: Atrial flutter with 1:1 conduction to the ventricles is a dangerous cardiac arrhythmia. Contemporary guidelines recommend atrioventricular nodal blocking agents should be co-administered with class 1C anti-arrhythmics, as prophylaxis against 1:1 flutter. No guidance is provided on the ...
