脉冲场移除 (PFA) 显示了与热移除相比,通过减少心律失常的复发来治疗心房动 (AF) 的前景. 虽然观察性研究表明有显著的益处,但随机对照试验表明更温和,但仍然是积极的结果,没有增加安全问题.
科学领域:
- 心脏病学 心脏病学
- 医疗器械 医疗器械
- 电力生理学 电力生理学
背景情况:
- 前庭动 (AF) 的管理通常涉及导管切除.
- 脉冲场切除 (PFA) 是一种新的非热方法.
- 将PFA与传统的热除进行比较对于临床决策至关重要.
研究的目的:
- 为了评估PFA的疗效和安全性与AF治疗的热废除相比.
- 为了比较PFA和热消光之间的复发率和程序特征.
- 评估在AF患者中PFA的时间到效益和临床意义.
主要方法:
- 在PubMed,Embase和Cochrane数据库中进行了系统的文献搜索,直到2025年7月.
- 分析了个别患者的数据,使用考克斯脆弱性回归来分析时间到事件的结果.
- 贝叶斯随机效应模型被用于研究水平的疗效和安全的元分析.
主要成果:
- 包括12项研究 (4项RCT,8项观察性) 涉及3,120名患者.
- 与热性废除相比,PFA显示出更高的无心律失常复发率 (HR 0.68).
- PFA与更短的手术和左心房停留时间有关,没有观察到增加的安全风险.
结论:
- 与热性除相比,脉冲场除与AF患者心律失常复发的减少有关.
- 观察到的PFA的益处在观察性研究中比在RCT中更为明显.
- PFA似乎是AF导管切除的安全替代品,没有增加危害的信号.

Pulse Rate and its Significance
Pulse rate, often measured in beats per minute (bpm), reflects the heart rate (HR), which is influenced by numerous factors such as stress, physical activity, and hormonal changes. A normal resting adult pulse rate falls...

Cardiac Action Potential
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.

Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...
