Visualizing Localized Reentry With Ultra-High Density Mapping in Iatrogenic Atrial Tachycardia: Beware Pseudo-Reentry.
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 activation patterns in LR. METHODS AND RESULTS LR was suggested by small rotatory activations (carousels) containing the full spectrum of the color-coded map. Twenty-three left-sided atrial tachycardias were mapped i...
متن کاملFocus, reentry, or "focal" reentry?
THE QUESTION WHETHER tachyarrhythmias are caused by enhanced impulse formation (“focus”) or by reentrant excitation (“reentry”) has been the subject of debate for more than a century. In 1887 McWilliam (12) was the first to suggest that disturbances in impulse propagation could be responsible for fibrillation, and he clearly envisaged the possibility that myocardial fibers could be reexcited as...
متن کاملCryoablation for atrioventricular nodal reentry tachycardia: Role of “mapping” and “pseudo-mapping”
The goal of catheter ablation is to create lesions that would cause local tissue destruction and thus eliminate or modify arrhythmia substrate. This is commonly accomplished by changing cellular temperature at two extremes by either heating or cooling with radiofrequency (RF) and cryothermal energy respectively. Both RF and cryoablation technologies are widely available. It is because of the “c...
متن کاملPseudo cryomapping for ablation of atrioventricular nodal reentry tachycardia: A single center North American experience
BACKGROUND Most literature for cryoablation of atrioventricular nodal reentry tachycardia (AVNRT) is based on -30 degree celsius cryomapping with 4 & 6 mm distal electrode catheters. The cryomapping mode is not available on the 6 mm cryocatheter in the United States. We describe a technique for 'pseudo' mapping at -80° using a 6 mm cryocatheter and report on short and long term outcomes. METH...
متن کاملMapping Reentry
• Small-circuit reentry (microreentry) in which extremely slow conduction in a focal area sustains the reentry also presents with centrifugal activation. Unlike automaticity, however, the local bipolar electrograms at the site of the apparent focal source are fragmented and abnormal with microreentry. • When mapping 1 chamber, say the right atrium, but a macroreentry circuit is located within t...
