Pulse rhythm01:30

Pulse rhythm

768
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

科学领域:

  • 心脏病学 心脏病学
  • 生物医学工程 生物医学工程
  • 医疗器械 医疗器械

背景情况:

  • 阿维尔DR是一个新的双室无心脏起器 (LP) 系统.
  • 它使用不同的无线心房和心室LP (ALP,VLP) 进行心房同步节奏.
  • 慢性植入物到植入物 (i2i) 传输成功率需要系统评估.

研究的目的:

  • 在临床环境中评估无线植入物到植入物 (i2i) 传输的慢性成功率.
  • 评估心房和心室无心脏起器之间的通信可靠性.

主要方法:

  • 展望的国际临床试验 (Aveir DR i2i研究) 涉及399名患者.
  • 在i2i传输成功率 (A-to-V和V-to-A) 的质疑在植入,放电以及植入后的1,3,6个月.
  • 分析包括具有标准双室节奏指示的患者.

主要成果:

  • 在6个月的随访期间,i2i成功率的中位数超过了90%的节拍.
  • 初始低i2i成功率 (<70%) 的患者在1个月内显著改善.
  • 在6个月后,只有大约5%的患者经历了持续的低i2i成功.

结论:

  • 阿维尔DR无线起器系统实现了高 (>90%) 的无线i2i通信成功.
  • 随着时间的推移,通信可靠性得到改善,特别是在最初面临挑战的子组中.
  • 这证明了无双室节奏技术的临床可行性.
