BACKGROUND
Consistent detection of rotor(s) and/or focal impulse(s) of atrial fibrillation can using a 64-pole basket catheter remain unclear.
METHODS AND RESULTS
Intracardiac left atrial electrograms were recorded, prior to ablation, in 20 patients with atrial fibrillation. Unipolar electrograms, filtered at 0.1-300 Hz, were recorded and exported for an offline phase analysis. From the cohort, 8 of the 20 patients had analyzable data. Localized rotors were identified in 3 of these patients, with focal impulses detected in 4 patients.
CONCLUSION
Localized rotors and focal impulses can be identified on phase maps of atrial fibrillation in a small number of patients.
背景
使用64极篮状导管能否持续检测到心房颤动的转子和/或局灶性冲动仍不清楚。
方法与结果
在20例心房颤动患者消融术前记录心腔内左心房电图。记录经0.1 - 300Hz滤波的单极电图，并导出用于离线相位分析。在该队列中，20例患者中有8例具有可分析的数据。其中3例患者识别出局部转子，4例患者检测到局灶性冲动。
结论
在少数心房颤动患者的相位图上可识别出局部转子和局灶性冲动。
