Transient entrainment of tachycardias.
A bout 15 years ago, Waldo and associates' first described that a tachycardia could be transiently accelerated to a faster rate by overdrive pacing without fundamentally altering the underlying tachycardia, a phenomenon they called transient entrainment. That first description of transient entrainment applied to atrial flutter but was soon extended to ectopic atrial tachycardias,2 atrioventricu...
متن کاملIatrogenic Left Atrial Tachycardias
epending on initial ablative approach, the incidence of left trial tachycardia (LAT) or flutter after atrial fibrillation AF) ablation has varied about 10-fold. Using segmental, stial pulmonary vein (PV) and/or antral isolation, about 3% f patients require repeat ablation for LAT (1,2). Conersely, using widely encircling PV lines plus mitral and roof ines, LAT incidence is often 20% to 30% (3,4...
متن کاملAtrial Tachycardias Following Atrial Fibrillation Ablation
One of the most important proarrhythmic complications after left atrial (LA) ablation is regular atrial tachycardia (AT) or flutter. Those tachycardias that occur after atrial fibrillation (AF) ablation can cause even more severe symptoms than those from the original arrhythmia prior to the index ablation procedure since they are often incessant and associated with rapid ventricular response. D...
متن کاملMultiple atrial tachycardias after atrial fibrillation ablation: the importance of careful mapping and observation.
A combination of pulmonary vein isolation (PV), electrogram-based ablation, and linear lesions have been demonstrated to result in medium-term freedom from atrial fibrillation (AF) in the majority of patients with persistent AF in several studies. Such an extensive ablation is associated with a high incidence of postablation atrial tachycardia (AT), which is often complex and multiple. Deductiv...
متن کاملElectroanatomical mapping for visualization of atrial activation in patients with incisional atrial tachycardias.
AIMS Incisional atrial tachycardias in patients following surgery for congenital heart disease are based on complex structural abnormalities in these hearts. The aim of this study was to evaluate the use of the electroanatomical mapping system, CARTO, in consecutive patients with different forms of incisional atrial tachycardia. METHODS AND RESULTS The electroanatomical mapping system combine...
