Anatomic determinants of atrial arrhythmias: New insights from three-dimensional mapping.
The recent development of new technologies for in vivo three-dimensional mapping of arrhythmias has enabled a better understanding of the richness of intracardiac anatomy and the relationship between anatomy and arrhythmogenesis. In the present manuscript we review two new technologies for in vivo mapping of atrial arrhythmias and explores the degree to which the anatomic complexity they reveal is important in determining the physiology of both focal and macroreentrant atrial tachycardias. These observations highlight the importance of including sufficient anatomic detail in modeling studies aimed at elucidating the pathophysiology of atrial arrhythmias.
