科学领域:

  • 心脏病学 心脏病学
  • 电子生理学 电子生理学
  • 医疗器械 医疗器械

背景情况:

  • 闭环刺激 (CLS) 是一种使用心内阻抗的速度响应节奏算法.
  • 它在传导系统加速,特别是左捆分支区域加速 (LBBAP) 中的有效性仍未得到研究.
  • 慢性无能需要响应速度的节奏解决方案.

研究的目的:

  • 在接受LBBAP的患者中评估CLS的速度响应性能.
  • 评估CLS与LBBAP是否可以在日常生活中实现适当的心率 (HR) 分布.
  • 为了将CLS-LBBAP与LBBAP患者的传统DDD节奏进行比较.

主要方法:

  • 这是一项回顾性研究,比较了24名患有CLS-LBBAP的患者和19名患有DDD-LBBAP的患者.
  • 通过设备查询收集的数据,至少需要30天的随访时间.
  • 分析累积HR分布和HR的平均值.

主要成果:

  • 与DDD-LBBAP相比,CLS-LBBAP显示了较高的心房节奏百分比 (58%对13%,p=0.001).
  • 在所有心率频率容器中观察到CLS节奏的跳动.
  • 两组之间的节拍分布 (p=0.643) 或平均HR (72bpm vs. 73bpm,p=0.615) 没有显著差异.

结论:

  • 在一个广泛的频率范围内,CLS有效调节LBBAP中的节奏率.
  • 在LBBAP的领先地位不会对CLS的表现产生负面影响.
  • CLS是适合LBBAP的速度响应算法,提供与DDD节奏相比较的HR控制.
