La clasificaciГіn tradicional que distingue la taquicardia auricular del aleteo auricular basГЎndose en criterios de frecuencia y morfologГa de ondas ha dejado de ser relevante, en un momento en que el desarrollo de la electrofisiologГa clГnica puede permitir una intervenciГіn curativa sobre la arritmia, basada en su mecanismo, y se hace muy necesario acercar la experiencia del laboratorio a la clГnica. Some of the concepts may seem complex, but we thought it important to provide an overview of the electrophysiological methods that may eventually lead to the description of the anatomic bases of the arrhythmias currently, these are easier to understand thanks to the virtual anatomic casts built using computerized navigation systems.Д®n el aГ±o 2009 se llevaron a cabo en EspaГ±a 2.343 procedimientos de ablaciГіn con catГ©ter de aleteo, taquicardia macrorreentrante atГpica o taquicardia auricular focal, con un crecimiento del 8% sobre el aГ±o anterior, lo que da una idea de la importancia clГnica de estas arritmias. In this review we outline our present understanding of atrial tachycardia mechanisms, both focal and macroreentrant, and attempt to establish the conceptual links with classic concepts that may help the clinician to make a differential diagnosis and establish therapeutic indications, including that of an electrophysiologic study. The classic categorization of atrial tachycardia and atrial flutter based on rate and morphological criteria has become almost irrelevant at a time when clinical electrophysiology may lead to curative intervention based on a definition of the mechanism, making it necessary to bring laboratory experience closer to clinical practice.

In 2009, 2343 catheter ablation procedures were performed in Spain for focal atrial tachycardia or atrial flutter (typical and atypical), with a yearly growth rate of 8%, indicating the clinical importance of these arrhythmias.
