Global distribution of atrial ectopic foci triggering recurrence of atrial tachyarrhythmia after electrical cardioversion of long-standing atrial fibrillation: a bi-atrial basket mapping study.
نویسندگان
چکیده
OBJECTIVES The objective of this study was to assess the spatial distribution of atrial ectopic foci potentially triggering recurrent atrial tachyarrhythmias after electrical cardioversion of long-standing atrial fibrillation (AF). BACKGROUND It remains unknown whether targeted ablation of atrial ectopic foci concentrated in the pulmonary veins is feasible in patients with long-standin

Reversal atrial electrical remodeling following cardioversion of long-standing lone atrial fibrillation.
BACKGROUND Atrial fibrillation (AF) itself promotes electrophysiological changes, termed 'electrical remodeling', facilitating its recurrence and maintenance. There is evidence that the remodeling process is reversible after restoration of the sinus rhythm (SR). However, the timing for the recovery of electrophysiological properties is still undefined. OBJECTIVE The aim of this study was to a...

Atrial Fibrillation is a supra ventricular tachyarrhythmia, which is characterized by the deterioration of atrial mechanical function and aberrant. It has become a social and economic problem because a large percentage of the world population suffering from this disease. The early diagnosis of this fatal cardiac Arrhythmia can be prevented and managed it. In this study, we used non-invasive met...

Objectives: Dual pathways have a determinant role in the occurrence of atrio nodal tachyarrhythmia (AVNRT). The aim of present study is to determine the role of slow pathway (SP) in the concealment zone and protective role of AV node during atrial fibrillation (AF). Material &Methods: In 7 isolated nodal rabbit preparation zone of concealment and concealed conduction is quantified by Specif...

Introduction: Most current evidence suggests the risk of left atrial and or auricular thrombi(LA &LAA) in patients with atrial flutter rhythm is similar to patients with atrial fibrillation, but there is still uncertainty in the risk level and the patient's need to receive anticoagulant therapy. Different studies report various frequencies for atrial thrombi and left atrial spontaneous echo-con...
