概括
导电系统节奏 (CSP) 显示了非常低的节奏诱导心肌病 (PICM) 的发生率,保持心室功能. 他的捆绑节奏和左捆绑分支区域节奏都提供了类似的保护,防止不良的心脏重塑.
科学领域:
- 心脏病学 心脏病学
- 电子生理学 电子生理学
- 心脏成像 - - 心脏成像
背景情况:
- 与传统方法相比,导电系统节奏 (CSP) 可能会降低节奏诱导心肌病 (PICM) 的发生率.
- 以前的研究主要关注左心室的影响,需要对所有心室进行全面评估.
研究的目的:
- 为了评估中期心声学变化心脏形态和功能在所有心脏腔室中,在CSP后的患者中保存到中等范围的LVEF.
- 为了比较他的捆绑节奏 (HBP) 与左捆绑分支区域节奏 (LBBAP) 对心脏参数的影响.
主要方法:
- 预期招募128名患有LVEF>40%的患者,他们成功接受了CSP,以治疗肌节律不良.
- 在基线和随访 (平均699天) 完成2D心声回声,以评估心室体积,喷射率和腔室尺寸.
- 将患者分为HBP (n=38) 和LBBAP (n=90) 组进行分类.
主要成果:
- 观察到非常低的PICM发病率 (2.9%).
- CSP显著增加了LVEF,并降低了左心室末端透缩和末端静缩体积.
- 右心室功能显著改善,心房体积或RV直径没有显著变化. 三椎吐显示情况恶化.
- 在HBP和LBBAP组之间没有发现显著的心声学差异.
结论:
- 无论是HBP还是LBBAP,在所有心室中都显示出相似的保护作用,防止不良心脏重塑.
- 脑脊髓炎与PICM的患病率非常低有关,即使在基线维持到中等范围的LVEF的患者中也是如此.

Imaging Studies for Cardiovascular System I:Echocardiography
294
Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...

Pathophysiology of Cardiac Performance
542
Typical heart performance is influenced by heart rate, rhythm, myocardial contraction, and metabolism or blood flow. The cardiac muscle exhibits distinct electrophysiological features, including pacemaker activity and calcium channel control, which play a vital role in the heart's response to various drugs. The autonomic nervous system, comprising the sympathetic and parasympathetic branches, regulates heart rate. Sympathetic activation increases heart rate, while parasympathetic activation...
