概括

电图流 (EGF) 地图识别了60%接受重复切除术的患者中心房动 (AF) 的来源. 与单独的肺静脉隔离相比,EGF引导的切除显著改善了无AF生存率.

科学领域:

心脏病学心脏病学
电力生理学电力生理学
医疗器械医疗器械

背景情况:

心房动 (AF) 的管理通常需要识别和切除非肺静脉来源.
电图流 (EGF) 映射提供了波面传播的时空重建,以确定这些AF源.

研究的目的:

评估Ablacon电图流 (EGF) 算法技术 (Ablamap软件) 在识别AF源方面的可靠性.
使用EGF映射在经历重复手术的持久性AF患者中指导切除疗法.
通过EGF指导的废除策略,改善AF复发的结果.

主要方法:

在FLOW-AF研究中,纳入了经过重复切除的持续性AF患者.
进行了EGF映射,具有显著源活性的患者被随机分配到PVI + EGF引导性切除或单独PVI.
随访包括3,6个月和12个月的心电图监测.

主要成果:

在EGF绘制的地图中,在接受重复切除术的60%的患者中确定了AF源.
消除已识别的EGF来源的成功率为95%.
在12个月后,EGF导向切除组的无关节炎生存率为68%,对照组为17% (P=0.042).

结论:

在经过重复切除的患者中,EGF映射有效地识别了肺外静脉AF源.
与单独的标准PVI相比,EGF引导的切除显著改善了AF无生存率.
阿布拉康EGF技术在指导AF移除疗法方面表现出可靠性.

Disturbances in Heart Rhythm

Disturbances in Heart Rhythm

Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...

Dysrhythmias VI: Management of Dysrhythmias

Dysrhythmia management involves a multifaceted approach, incorporating pharmacological treatments, medical procedures, surgical interventions, lifestyle modifications, and patient education.Pharmacological ManagementAntiarrhythmic Drugs:Class I (Sodium Channel Blockers): This class includes quinidine and procainamide, which reduce the speed of impulse conduction in the heart, stabilize the cardiac membrane, and control arrhythmias. Quinidine and procainamide are Class IA agents that prolong the...
