摘要:
目的 探索左心耳电压分布规律及其与心房颤动的关系。方法 纳入2016年6月—2018年1月在成都市第三人民医院行三维电解剖标测的病例,分为非房颤组(n=43)、阵发性房颤组(n=44)和持续性房颤组(n=39),在三维电解剖系统指导下(CARTO 3),使用标测导管(PentaRay)采集左心耳各位点电压,进行三组左心耳电压分布分析。结果 三组人群符合正态分布的例数分别为非房颤组6(14.0%)、阵发性房颤组0(0.0%)、持续性房颤组0(0.0%);三组间左心耳电压分布具有统计学差异,三组左心耳均值电压分别为非房颤3.51 mV、阵发性房颤2.57 mV、持续性房颤2.22 mV,(P<0.001)。结论 左心耳电压分布形态具有个体间稳定性;房颤的发生与进展并不影响左心耳电压的分布形态,但会下调心耳电压值的平均水平与高位水平。
Abstract:
Objective To explore the voltage distribution of left atrial appendage(LAA) and its relationship with atrial fibrillation. Methods Patients who underwent three-dimensional electro-anatomic mapping(EAM) during June 2016 to January 2018 in The Third People’s Hospital of Chengdu were divided into three groups: non-atrial fibrillation group(n=43), paroxysmal atrial fibrillation group(n=44) and persistent atrial fibrillation group(n=39). CARTO 3 system and PentaRay Cather were used for EAM, and the voltage distribution of LAA was analyzed . Results The cases in the three groups meeting the normal distribution were 6(14.0%) in the non-atrial fibrillation group, 0(0.0%) in the paroxysmal atrial fibrillation group, and 0(0.0%) in the persistent atrial fibrillation group. The voltage distribution of LAA was statistically different among the three groups. The voltage distribution of the LAA was statistically different among the three groups. The mean voltage of the LAA in the three groups was 3.51 mV for non-atrial fibrillation, 2.57 mV for paroxysmal atrial fibrillation and 2.22 mV for persistent atrial fibrillation(P<0.001). Conclusion The voltage distribution pattern of the LAA is inter-individual stable. The occurrence and progression of atrial fibrillation do not affect the distribution pattern of the voltage of the LAA, but it can lower the average level and the high level of the voltage of the LAA.
