概括

在心脏起器植入后,双室 (DDD) 节奏在全心房阻塞患者中比心室 (VVI) 节奏更好地保持左心室功能,显示出显著的全球纵向应变改善.

科学领域:

心脏病学心脏病学
电力生理学电力生理学
心脏成像 - - 心脏成像

背景情况:

整体心房阻塞 (TAVB) 需要永久心脏起器植入 (PPM).
双室 (DDD) 节奏在理论上比心室 (VVI) 节奏更生理,但临床优势仍然未被证明.
使用全球纵向应变 (GLS) 评估左心室 (LV) 功能对于评估节奏模式至关重要.

研究的目的:

为了比较DDD与VVI节拍对TAVB患者的LV功能的影响.
评估PPM植入后1个月和3个月GLS的变化.

主要方法:

一项对成人TAVB患者进行PPM植入的比较研究.
在PPM之前,在PPM后1个月和3个月进行了心声学GLS测量.
分析了符合纳入标准的43名患者,比较了DDD和VVI节奏模式.

主要成果:

在DDD和VVI组之间没有观察到显著的基线差异.
在VVI组中,PPM后1个月发生了显著的GLS恶化 (P=0.002).
在DDD组中没有观察到任何显著的GLS变化,即使在3个月后 (P=0.055).

结论:

在PPM后的TAVB患者中,DDD节奏显示在维护LV功能的短期优势.
这些发现表明,DDD节奏可能有利于在TAVB中维持心脏力学.
需要进一步的长期研究来证实这些益处.

关键词:

Dysrhythmias IV: Characteristics of Bradyarrhythmias

Bradyarrhythmias are cardiac rhythm disorders characterized by a slower-than-normal heart rate, typically defined as fewer than 60 beats per minute. Some of which are discussed here:Sinus BradycardiaSinus bradycardia presents a heart rate lower than 60 beats per minute, with a regular rhythm originating from the SA node. The ECG typically shows normal P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and a normal QRS duration (0.06 to 0.10 seconds).First-Degree AV...
