对于心房动的导管切除会导致心率和自主功能的持久变化,这与使用的技术无关. 这些自主变化与成功控制心律失常有关.
科学领域:
- 心脏病学 心脏病学
- 自主神经系统的自主神经系统
- 电子生理学 电子生理学
背景情况:
- 导管切除对心脏自主系统的长期影响尚不清楚.
- 动性心房的管理往往涉及导管切除对于耐火病例.
研究的目的:
- 研究热导管切除对心脏自主功能的长期影响.
- 为了评估心率变化 (HRV) 和心率在剥离后的变化.
主要方法:
- 346名患有心脏动症的患者通过使用射频或冷热气球移除进行了肺静脉隔离.
- 植入式心脏监测器记录了HRV,白天心率和夜间心率 (NHR) 在切除后3年.
- 取消前的自主数据与取消后的数据进行了比较.
主要成果:
- 在切除后观察到HRV的显著下降以及白天和夜间心率的增加.
- 自主变化在前3个月最明显,但持续了36个月.
- 较大的NHR和HRV变化与更好地摆脱复发性心房动有关.
结论:
- 对心房动的热导管切除导致自主心率参数持续,显著的变化.
- 这些自主变化是一致的,不管是废弃的能量来源 (射频或冷却气球).
- 观察到的自主修饰与肺静脉隔离程序的成功有关.

In spin–lattice or longitudinal relaxation, the excited spins exchange energy with the surrounding lattice as they return to the lower energy level. Among several mechanisms that contribute to spin–lattice relaxation, magnetic dipolar interactions are significant. Here, the excited nucleus transfers energy to a nearby...
