Abstract

BACKGROUND

Effects of nonparoxysmal atrial fibrillation (non-PAF) ablation targeting complex fractionated atrial electrogram (CFAE) areas and/or low voltage areas (LVAs) are still controversial.

METHODS AND RESULTS

A recently developed online real-time phase mapping system (ExTRa Mapping) was used to conduct LVA mapping and simultaneous ExTRa and CFAE mapping in 28 non-PAF patients after pulmonary vein isolation (PVI). Nonpassively activated areas, in the form of meandering rotors and/or multiple wavelets assumed to contain non-PAF drivers, partly overlapped with CFAE/LVAs but not always coincided with them.

CONCLUSION

Real-time rotor imaging, rather than conventional indirect indicators only, might be very useful for detecting non-PAF drivers.

摘要

背景

针对复杂碎裂心房电图（CFAE）区域和/或低电压区域（LVA）进行非阵发性心房颤动（non-PAF）消融的效果仍存在争议。

方法与结果

使用一种最近开发的在线实时相位标测系统（ExTRa Mapping），对28例肺静脉隔离（PVI）后的非PAF患者进行LVA标测以及同步的ExTRa和CFAE标测。以蜿蜒转子和/或多个小波形式存在的非被动激活区域，被认为包含非PAF驱动因素，部分与CFAE/LVA重叠，但并非总是与之重合。

结论

实时转子成像，而非仅传统的间接指标，可能对检测非PAF驱动因素非常有用。
