概括
闭环刺激 (CLS) 通过左捆分支区域节奏 (LBBAP) 有效地调整心率 (HR),与DDD节奏相比显示类似的HR分布和平均HR. 这表明CLS是LBBAP的可行的利率响应选择.
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.

01:20Motor Unit Stimulation
When the neuron of a motor unit fires an action potential, it triggers a series of events, leading to a twitch contraction in the muscle fibers. The process of excitation-contraction coupling is crucial in relaying the action potential to the muscle fibers.
The latent period of contraction marks the onset of excitation-contraction coupling, when the action potential propagates across the sarcolemma, preparing the muscle fibers for contraction. As the fibers enter the contraction phase, the...
