概括
脊心脂肪组织 (EAT) 的体积在患有胸腺节律不良的患者中显著增加. 增加的EAT体积与心房阻塞的严重程度相关,这表明EAT是管理心律失常的潜在目标.
科学领域:
- 心脏病学 心脏病学
- 医疗成像医学成像
- 生物医学研究生物医学研究
背景情况:
- 心脂肪组织 (EAT) 与前节律不良的影响有关,特别是动脉节律不良.
- 人们对EAT和节律不良之间的关联仍然不太了解.
- 这项研究探讨了EAT和勃拉迪亚心律失常症之间的关系.
研究的目的:
- 探索心表脂肪组织 (EAT) 与肌节律不良之间的关联.
- 为了确定EAT的体积或密度是否是勃拉地心律不良发展的重要因素.
- 为了检查EAT和心房阻塞 (AVB) 的程度之间的相关性.
主要方法:
- 胸部计算机断层扫描 (CT) 扫描的回顾性分析来自652名患者 (326名患有肌节律不良,326名对照).
- 使用手动心周围线轮跟踪和标准化Hounsfield单位值 (-200 到 -50 HU) 来量化EAT体积和密度.
- 案例匹配的控制设计与有条件的物流分析和斯皮尔曼对 PR 间隔分析的相关性.
主要成果:
- 与对照组相比,不良心律患者的EAT体积显著增加 (119.13cm3 vs. 93.00cm3,P<0.001) 和EAT密度降低 (-92.02HU vs. -90.68HU,P<0.001).与对照组相比,不良心律患者的EAT体积显著增加 (119.13cm3 vs.
- EAT的体积,而不是密度,被确定为白节律不良的重要影响因素.
- 随着心房阻塞 (AVB) 的进展,观察到EAT体积的逐渐增加,在一级AVB中,PR间隔和EAT体积之间存在正相关性 (r=0.328,P=0.012).
结论:
- 较高的上心脂肪组织 (EAT) 体积显着与肌节律不良有关.
- 在EAT负担和导电系统损伤之间存在剂量依赖的关系.
- EAT可能是心律失常的可修改因素,因此需要进一步研究有针对性的减肥策略.

Dysrhythmias IV: Characteristics of Bradyarrhythmias
474
Bradyarrhythmias are cardiac rhythm disorders characterized by a slower-than-normal heart rate, typically defined as fewer than 60 beats per minute. Some of which are discussed here:Sinus BradycardiaSinus bradycardia presents a heart rate lower than 60 beats per minute, with a regular rhythm originating from the SA node. The ECG typically shows normal P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and a normal QRS duration (0.06 to 0.10 seconds).First-Degree AV...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias
433
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...

Mechanism of Cardiac Arrhythmias
1.6K
Arrhythmias are irregular heart rhythms occurring when the heart's electrical impulses become abnormal. These disturbances can lead to various symptoms, depending on their severity and the underlying cause. Some common factors contributing to arrhythmias include hypoxia, ischemia, electrolyte imbalances, excessive catecholamine exposure, drug toxicity, and muscle overstretching. Arrhythmias can be classified into two main types based on the rate and site of origin of abnormal heart rhythms.

ECG Interpretation of Arrhythmias I: Sinus Arrhythmias
724
Arrhythmias are disturbances in the heart's rhythm that lead to abnormal heartbeats. These irregularities can originate from different parts of the heart and are classified based on their origin and nature.
Types of Arrhythmias
Sinus Node Arrhythmias
Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism,...
