Ultra-high-definition mapping for atrial arrhythmias allowed the automatic acquisition of an average of 13,724 electrograms per map in 16.9 minutes, facilitating precise identification of critical isthmuses.
Ultra-high-definition mapping provides rapid, high-resolution, automatic electrogram acquisition that improves the identification of critical isthmuses and scar tissue during atrial arrhythmia ablation.
The advantages of ultra-high-definition (UHD) mapping are presented in the context of different atrial arrhythmias, whether focal or macroreentrant. Not only are these sophisticated systems time-saving, but they also allow accurate identification of the substrate (scar quantification), as well as a more precise characterization of the critical isthmuses or focal sources of the atrial circuits. UHD mapping may become a standard approach for their curative treatment. This new technology allows automatic acquisition and accurate annotation of the electrograms, without the need for manual correction. Owing to better resolution, critical isthmuses and low-voltage regions of interest may now be successfully targeted without the need for entrainment maneuvers. Finally, the system also allows rapid assessment of the completeness of the lesions once delivered. (Circ J 2016; 80: 579-586).
Bun et al. (Fri,)는 심방 부정맥에 대한 리뷰를 수행했습니다 (n=46). 평균 맵당 맵핑 시간(분)에 대한 초고해상도(UHD) 맵핑이 평가되었습니다. 심방 부정맥을 위한 초고해상도 맵핑은 16.9분 동안 맵당 평균 13,724개의 전기생리학적 신호를 자동으로 수집할 수 있게 하여 중요한 좁은 부위를 정밀하게 식별할 수 있도록 도왔습니다.
