Supraventricular arrhythmias are common and patients are often symptomatic, requiring
management with drugs and electrophysiological procedures. The ESC published …

Objectives: This study reports the use of a novel “Lumipoint” algorithm in ventricular
tachycardia (VT) ablation. Background: Automatic mapping systems aid rapid acquisition of …

Introduction Accurate identification of slow conducting regions in patients with scar‐related
atrial tachycardia (AT) is difficult using conventional electrogram annotation for cardiac …

Background—The activation pattern of localized reentry (LR) in atrial tachycardia remains
incompletely understood. We used the ultra–high density Rhythmia mapping system to study …

Contact mapping of cardiac arrhythmias evolved in the past 2 decades from fluoroscopic
catheter manipulation and manual detection of the local activation time (LAT) to 3-D point-by …

Ripple mapping is a novel method of 3D intracardiac electrogram visualisation that allows
activation of the myocardium to be tracked visually without prior assignment of local …

Background—Post-infarct ventricular tachycardia is associated with channels of surviving
myocardium within scar characterized by fractionated and low-amplitude signals usually …

Background Radiofrequency catheter ablation for atrial fibrillation (AF) without using
fluoroscopy has been getting popular. In this study, we reported the transition period …

Background: Ripple mapping (RM) is an alternative approach to activation mapping of atrial
tachycardia (AT) that avoids electrogram annotation. We tested whether RM is superior to …

Objectives The authors reviewed 3-dimensional electroanatomic maps of perimitral flutter to
identify scar-related isthmuses and determine their effectiveness as ablation sites …
