Pace mapping for the localization of focal atrial tachycardia arising near the mitral annulus.
Of the various therapeutic modalities available to treat ectopic atrial tachycardia, radiofrequency catheter ablation has shown excellent results. It is usually possible to localize the earliest site of endocardial activation by conventional or newer three-dimensional mapping techniques. We report a case of ectopic atrial tachycardia, wherein the tachycardia was being repeatedly interrupted by mechanical trauma. Finally, with the help of P wave pace mapping, the tachycardia was localized near the posterolateral part of the mitral annulus, and successfully ablated. This report demonstrates the utility of P wave pace mapping in ectopic atrial tachycardia.
