The purposes of the study were to evaluate and characterize the cavotricuspid isthmus using multipoint high density voltage gradient mapping (HD-VGM) to see if this would improve on current ablation techniques compared to standard cavotricuspid isthmus ablation techniques. Group 1, 25 patients who underwent ablation using standard methods of 3D mapping and(More)
Introduction High-density (HD) mapping of tachycardias can be helpful in identifying the circuits in complex arrhythmias. It has also been shown to be helpful in identifying the slow pathway in atrioventricular nodal reentrant tachycardia (AVNRT). We participated in the NODE-1 study, which was a multicenter, placebo-controlled, double-blinded, dose-ranging(More)
This study aims to describe a novel method of High Density Activation Sequence Mapping combined with Voltage Gradient Mapping Overlay (HD-VGM) to quickly localize and terminate atypical atrial flutter. Twenty-one patients presenting with 26 different atypical atrial flutter circuits after a previous catheter or surgical AF ablation were studied. HD-VGM was(More)
