概括

两心管 (Bi-V) 节奏可能会增加导管切除 (CA) 后心室低心率 (VT) 的复发,特别是侧壁VT起源. 这一发现对于管理正在接受静脉管切除和节律调节的结构性心脏病患者至关重要.

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:

双心室 (Bi-V) 节奏增强左心室 (LV) 功能,通过解决异步.
然而,Bi-V节奏带有潜在的前节律失常风险.
双-V节奏对心室动脉冲动 (VT) 复发后导管切除 (CA) 的影响尚未明确.

研究的目的:

评估Bi-V节奏对结构性心脏病患者在CA后静脉瘤复发的影响.
分析基于VT起源的VT复发与Bi-V节奏相关.

主要方法:

一项比较研究包括384名为静脉瘤接受CA治疗的患者,分为Bi-V节奏 (≥90%节奏) 和内在节奏 (≤10%节奏) 组.
静脉瘤起源被分类为隔膜,侧面或前部/下部.
倾向性得分匹配确保了群体之间平衡的基线特征.

主要成果:

两组之间没有观察到所有原因死亡率或心力衰竭住院治疗的显著差异.
与内在节律组 (19.2%) 相比,VT / VF复发在Bi-V节律组 (37.0%) 中显著高于内在节律组 (19.2%).
在接受Bi-V刺激 (55.9%与21.9%) 的侧壁VT起源患者中,注意到VT复发率明显更高.

结论:

双V节奏,特别是在存在左心室侧壁基质的情况下,与导管切除后增加VT/VF复发有关.
侧壁VT起源与Bi-V节奏相结合,可以独立预测VT复发.

关键词:

双管节奏是双管节奏的节奏.有助于节律失常的效果这就是VT的废除.

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

Hormonal Regulation

Hormonal Regulation

Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

Anatomy of the Heart

Anatomy of the Heart

The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.
