概括

生物电子技术 (Biotronik) 是一种生物技术.

科学领域:

心脏病学心脏病学
生物医学工程生物医学工程

背景情况:

关于Biotronik的心室节拍抑制 (VpS) 和内在节律支持加 (IRSplus) 算法的个体内疗效的研究有限.
接受双腔心脏起器的症状性鼻节功能障碍 (SND) 患者是重点群体.

研究的目的:

评估VpS和IRSplus算法的有效性,以尽量减少心室节奏.
评估这些节奏最小化算法的安全性和有效性.

主要方法:

一个随机的试验试验,涉及韩国11家三级医院的131名患者.
患者在3个月的固定心房 (AV) 延迟期后随机分配到VpS或IRSplus.
主要结局:心室节奏百分比 (Vp%);次要结局:心力衰竭 (HF) 和心房动 (AF) 的发生率.

主要成果:

算法显著降低了平均Vp%从14.1%降至4.0%在9个月和6.7%在15个月.
节奏性AV延迟 (PAVD) ≤300毫秒的患者的疗效更高.
这两种算法在Vp%的减少中表现出同等的有效性,没有观察到AF或HF住院.

结论:

在SND患者中,VpS和IRSplus算法是有效和安全的,可以最大限度地减少不必要的心室节奏.
这些算法为优化这组患者的起器治疗提供了宝贵的工具.

Heart Failure II: Pathophysiology

Heart Failure II: Pathophysiology

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...
