概括
左心室隔膜节奏 (LVSP) 在接受心脏再同步治疗 (CRT) 的心力衰竭患者中显示出与左枝节奏 (LBBP) 相似的结果. 深隔膜节奏 (DSP) 与增加的不良事件有关.
科学领域:
- 心脏病学 心脏病学
- 电子生理学 电子生理学
- 心脏衰竭管理的管理
背景情况:
- 对于心力衰竭的左枝节拍 (LBBP) 和左心室隔膜节拍 (LVSP) 的结果需要进一步调查.
- 心脏再同步治疗 (CRT) 旨在改善心力衰竭的症状和结果.
研究的目的:
- 为了比较LBBP,LVSP和深隔膜节奏 (DSP) 的心声和临床结果.
- 在CRT候选人中评估不同隔膜刺激技术的疗效和安全性.
主要方法:
- 对91名符合CRT标准的患者进行了回顾性研究,这些患者接受了尝试LBBP.
- 数据收集包括在基线和随访时的临床,心电图和心声图参数.
- 患者被分为LBBP (n=52),LVSP (n=25) 和DSP (n=14) 组.
主要成果:
- 在LBBP和LVSP组中观察到显著的左心室喷射率 (LVEF) 改善 (P < .001).
- 在LBBP和LVSP组之间,心力衰竭住院或全因死亡没有显著差异.
- 与LBBP相比,DSP组的心力衰竭住院和全因死亡率增加 (HR 5.10,P=.033;HR 7.83,P=.020).
结论:
- 左心室隔膜节奏调节 (LVSP) 提供与心脏再同步治疗 (CRT) 结果相比较的左束枝节奏调节 (LBBP).
- 与LBBP相比,深隔膜节奏 (DSP) 与较差的临床结果有关.

01:30Pulse rhythm
795
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...

01:13The Cardiac Cycle
87.9K
The heart beats rhythmically in a sequence called the cardiac cycle—a rapid coordination of contraction (systole) and relaxation (diastole).
The Process
Electrical signals—sent from the sinoatrial (SA) node in the right atrial wall to the atrioventricular (AV) node between the right atrium and right ventricle—cause both atria to simultaneously contract. When the signal reaches the AV node, it pauses for approximately a tenth of a second, allowing the atria to contract and...
