IntroductionAtypical atrial flutter is a supraventricular arrhythmia that can be treated with catheter ablation. However, the best approach is still to be defined and this strategy has suboptimal results. The Carto(R) electroanatomical mapping (EAM) system can display a histogram of the local activation times (LAT) of the tachycardia cycle length (TCL). This study aimed to assess the ability of this new tool to identify the critical isthmus of this arrhythmia. MethodsRetrospective analysis of a...
