Pulse rhythm01:30

Pulse rhythm

777
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
  • 干预心脏病学 干预心脏病学
  • 医疗器械 医疗器械

背景情况:

  • 在识别和管理TAVR后导电障碍 (CD) 方面缺乏标准化,这可能会影响永久起器植入 (PPI) 率和临床结果.
  • 标准化TAVRCD算法的安全性和有效性以前没有被分析过.
  • 这项研究评估了Optimize PRO后TAVRCD管理算法与Evolut PRO/PRO+门结合使用.

研究的目的:

  • 分析Optimize PRO后TAVRCD管理算法的安全性和有效性.
  • 评估标准化算法的影响PPI率和TAVR后的临床结果.
  • 评估顶重叠技术和TAVR后的CD算法在降低心脏起器率方面的有效性.

主要方法:

  • 展望性,市场后研究 (优化PRO) 采用尖端重叠技术和TAVR后CD算法.
  • 患者接受了2小时的术后心电图,根据心电图的发现进行分层分离或CD算法.
  • CD算法解决了先前存在的或新的捆绑分支区块 (LBBB) 和心房门区块 (AVB).

主要成果:

  • 临时分析包括125名具有传导障碍 (CD) 的TAVR接受者.
  • 在CD队列中,30天新的PPI率为28.1%,对照组为1.5% (P <.001).
  • 在使用监视器出院的患者中,90%的患者不需要PPI;在患有CD和没有CD的患者中,临床结果相似.

结论:

  • 针对Evolut TAVR的标准化CD算法显示了安全的30天结果,与没有CD的患者相比.
  • 这种算法可以有效地早期识别心律失常,优化PPI利用率,并实现放出后安全的监测.
  • 在分析的队列中没有发生突然心脏病死亡.
