概括

大动脉膜疾病 (AVD) 改变了心率变化 (HRV) 的动态. 非线性分析显示,AVD患者的决定性和捕获时间增加,这表明与疾病严重程度相关的自主控制变硬.

科学领域:

心脏病学心脏病学
生物医学工程生物医学工程
身体生理学身体生理学

背景情况:

大动脉病 (AVD) 涉及炎症,脂质透和化.
动脉动脉疾病与改变的线性心率变化 (HRV) 指数有关,这表明交感主导和自主控制受损.

研究的目的:

用非线性方法,特别是复发量化分析 (RQA) 来研究AVD患者的HRV动态.

主要方法:

一项横截面研究包括127名受试者:健康的门 (HV),大动脉硬化症 (AVSc) 和大动脉狭窄症 (AVS).
在仰卧和站立的位置获得了五分钟的心电图记录.
使用交叉复发图表工具箱计算RQA指数.

主要成果:

大动脉狭窄症 (AVS) 患者的决定性和捕获时间较高,与躺卧的AVSc和HV组相比.
确定性和分层性逐渐从HV增加到AVS.
卧卧和站立位置之间的非线性HRV指数的变化随着AVD严重程度的增加而减少,在AVS中最低.

结论:

在AVD患者中HRV的RQA分析表明,随着越来越多的确定性和较少的状态的延长捕获时间,与AVD严重程度相关的硬化动态.
这些发现支持RQA方法在医学软件和用于AVD评估的设备中的潜在实施.

关键词:

大动脉狭窄症 (大动脉狭窄症)动脉样硬化症 (aortosclerosis) 是一种疾病.心脏自主调制的自主调制心率变化的心率变化.这是一个对静态挑战的挑战.复发图分析的复发图分析

Correlation between ECG and Cardiac Cycle

Correlation between ECG and Cardiac Cycle

The electrical signals recorded on an electrocardiogram (ECG) occur before the mechanical processes of contraction and relaxation during the cardiac cycle.
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
