概括
0/1小时算法准确地排除了心肌梗塞 (MI) 在心房动 (AF) 的患者. 然而,AF患者更常见,需要进一步的诊断评估.
科学领域:
- 心脏病学 心脏病学
- 紧急医疗 紧急医疗
- 诊断的准确性 诊断的准确性
背景情况:
- 心房动 (AF) 患者经常模仿急性冠状动脉综合征 (ACS) 症状.
- 在这两种情况中,心脏高灵敏度心脏托洛素 (hs-cTn) 的升高是常见的.
- 使用hs-cTn的0/1小时算法是心肌梗塞 (MI) 的快速诊断工具.
研究的目的:
- 评估胸痛患者0/1小时hs-cTn算法的诊断准确性.
- 评估算法的有效性,特别是在有或没有AF的患者中.
主要方法:
- 对DROP-ACS队列 (1333名患者) 的二次分析.
- 检查的诊断值:负预测值 (NPV),灵敏度,正预测值 (PPV) 和特异性.
- 在患有AF和没有AF的患者中比较算法性能.
主要成果:
- 患有AF的患者在"观察"组中更频繁 (54%vs34.9%),在"排除"组中更少 (24.1%vs44.6%).
- 该算法证明了100%的NPV和灵敏度,用于排除AF患者的MI.
- 在AF患者中,PPV和特异性较低 (分别为60%和89.7%).
结论:
- 0/1小时算法是安全和准确的,用于排除AF患者的心脏病发作.
- AF患者更有可能被分层到"观察"组.
- 需要进一步的研究,以确定AF患者的确诊.

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...

Disturbances in Heart Rhythm
857
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...
