概括

早期发现心房动 (AF) 是关键. 简单的心率变化指标,如pRR3.25%,对于AF检测是有效的,增加了复杂性,几乎没有实际好处.

科学领域:

心脏病学心脏病学
生物医学工程生物医学工程
信号处理信号处理

背景情况:

早期发现心房动 (AF) 对于预防中风至关重要.
心率变化 (HRV) 参数用于AF检测.
pRR30和pRR3.25%之前在区分AF与鼻节律 (SR) 中表现出强的表现.

研究的目的:

为了比较pRR30,pRR3.25%和AF检测的不对称的诊断特性.
为了评估不对称对现有的HRV参数的附加值.

主要方法:

从Physionet长期心房动数据库中的60秒心电图段中提取了RR间隔.
分析包括接收机操作员曲线分析,混矩阵和后勤回归.
评估了pRR30,pRR3.25%和不对称 (H) 的诊断特性.

主要成果:

组合模型 (pRR30,pRR3.25%,H) 的AUC为0.98,略高于pRR30 (0.959) 和pRR3.25% (0.972).
个别参数和组合模型之间的诊断性能实际差异可以忽略不计.
结合参数显著增加了假阴性病例的三倍.

结论:

不对称显示出在短ECG段中区分AF和SR的潜力.
将不对称添加到pRR30和pRR3.25%中,与单独的pRR3.25%相比,并没有显著改善AF检测.
pRR3.25%仍然是AF检测的高效参数.

关键词:

心房动是心房动的一种.心脏节律失常心脏节律失常电心电图 (ECG) 是一种心电图.进入的过程中,心率变化的心率变化.

Disturbances in Heart Rhythm

Disturbances in Heart Rhythm

Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow...

Pulse rhythm

Pulse rhythm

Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Pulse

Pulse

When the heart pumps blood out, arterial elastic fibers play a crucial role in sustaining a high-pressure gradient. They expand to accommodate the received blood and then recoil - a process known as the pulse that can be either manually palpated or electronically quantified. Despite a reduction in its effect with increased distance from the heart, elements of the pulse's systolic and diastolic components persist, observable even at the arteriole level.
The pulse serves as a clinical...
