概括

左捆分支区域节奏 (LBBAP) 和右心室节奏 (RVP) 可以导致心脏起器植入后静脉血压 (BP) 降低. 与RVP相比,LBBAP导致了更显著的BP降低.

科学领域:

心脏病学心脏病学
电子生理学电子生理学
心血管研究研究心血管研究

背景情况:

在左捆支部区域节奏 (LBBAP) 后,对血压 (BP) 变化的有限理解.
之前的研究集中在右心室节奏 (RVP) 和血压变化.
需要研究LBBAP与RVP的急性血液动力学影响.

研究的目的:

在LBBAP和RVP植入后评估急性血压 (BP) 变化.
为了比较LBBAP和RVP对患有胸肌梗塞的患者血压的影响.

主要方法:

单一中心对de-novo双腔心脏起器植入物的回顾性研究 (2019年1月 - 2021年6月).
倾向分数匹配 (PSM) 用于比较LBBAP和RVP组 (每组为193名患者).
在基线,0-24小时和植入后24-48小时进行的血压测量.

主要成果:

植入后观察到缩血压 (SBP) 的显著下降 (137.3至127.7 mmHg).
LBBAP组的SBP降低比RVP组更大 (11.6 mmHg对比7.6 mmHg).
在LBBAP患者中较高的SBP降低,具有高的SBP或不服用抗高血压药物.

结论:

永久心脏起器植入,特别是LBBAP,可能会急性降低缩血压.
与RVP相比,LBBAP的BP降低更为明显.
需要对LBBAP机制和长期血液动力学影响进行进一步的研究.

Measurement of Blood Pressure

Measurement of Blood Pressure

Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...
