Participation of atrial specialized conduction pathways in atrial flutter.
The circus movement theory of flutter has been supported by numerous theoretical, experimental, and clinical studies, but there has been little consideration of the possible participation of the specialized conduction pathways of the atria. In the present work we have studied experimental atrial flutter in relation to the behavior of these pathways, in response to elevated potassium and to surg...
متن کاملIbutilide added to propafenone for the conversion of atrial fibrillation and atrial flutter.
OBJECTIVES We evaluated the safety and efficacy of ibutilide when added to propafenone in treating both paroxysmal and chronic atrial fibrillation (AF) and atrial flutter (AFL). BACKGROUND The effects of ibutilide in patients with paroxysmal or chronic AF/AFL who were pre-treated with propafenone have not been previously evaluated. METHODS Oral propafenone was initially given in 202 patient...
متن کاملAtrial flutter with 1:1 A-V conduction.
To date, there have been fewer than 50 cases of atrial flutter with 1:1 A-V conduction documented in the English literature.1 The purpose of this paper is to emphasize the diagnostic facets of this relatively uncommon rapid ectopic rhythm and to review the pharmacology of the various therapeutic agents used in its treatment. Two additional cases of 1:1 atrial flutter are reported, one occurring...
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...
متن کاملIsoproterenol to evaluate resumption of conduction after right atrial isthmus ablation in type I atrial flutter.
BACKGROUND After radiofrequency (RF) ablation of atrial flutter (AFL), the demonstration of bidirectional isthmus conduction (BIC) block is considered the hallmark of a successful procedure. The purpose of our study was to test the persistence of BIC block after isoproterenol administration and to evaluate the importance of this finding with regard to AFL recurrences. METHODS AND RESULTS RF a...
