Two Independent Mapping Techniques Identify Rotational Activity Patterns at Sites of Local Termination During Persistent Atrial Fibrillation
INTRODUCTION The mechanisms for atrial fibrillation (AF) are unclear in part because diverse mapping techniques yield diverse maps, ranging from stable organized sources to highly disordered waves. We hypothesized that AF mechanisms may be clarified if mapping techniques were compared in the same patients, and referenced to a clinical endpoint. We compared two independent AF mapping techniques ...
متن کاملMapping of atrial fibrillation.
Cardiac mapping has been defined as: "a method by which cardiac signals are recorded from multiple sites of the heart and spatially depicted as a function of time in an integrated manner". It requires determination of the local activation time at each electrode and the creation of activation maps which provide a spatial model of the activation sequence. With respect to atrial fibrillation, mapp...
متن کاملSequential Hybrid Procedure for Persistent Atrial Fibrillation
BACKGROUND Catheter ablation of persistent atrial fibrillation yields an unsatisfactorily high number of failures. The hybrid approach has recently emerged as a technique that overcomes the limitations of both surgical and catheter procedures alone. METHODS AND RESULTS We investigated the sequential (staged) hybrid method, which consists of a surgical thoracoscopic radiofrequency ablation pro...
متن کاملMapping Atrial Fibrillation: 2015 Update.
Atrial fibrillation requires a trigger that initiates the arrhythmia and substrate that favors perpetuation. Cardiac mapping is necessary to locate triggers and substrate so that an ablation strategy can be optimized. The most commonly used cardiac mapping approach is isochronal or activation mapping, which aims to create a spatial model of electrical wavefront propagation. Historically, activa...
متن کاملMapping the Conversion of Atrial Flutter to Atrial Fibrillation and Atrial Fibrillation
It is not generally believed that there is a relation between atrial flutter, thought to be due to a single reentrant circuit, and atrial fibrillation, thought to be due to simultaneously circulating multiple-reentrant wave fronts. However, there are many reasons to suggest that these rhythms are more closely related than previously thought. To test the hypothesis that the length of an area of ...
