概括
设备检测到的心房动 (AF) 显示了持续时间和负担的显著波动. 大多数审讯显示,发作时间小于6小时或负担低于2%,即使是发作时间较长的患者. 需要更多的数据来指导基于这些波动的抗凝决定.
科学领域:
- 心脏病学 心脏病学
- 医疗器械 医疗器械
- 电力生理学 电力生理学
背景情况:
- 设备检测到的心房动 (AF) 经常导致基于持续时间或负担值的无限期抗凝药的建议.
- 然而,这些AF指标随时间的自发变异性尚未得到充分理解,这可能会影响治疗决策.
研究的目的:
- 量化植入式循环记录器 (ILR) 患者中AF持续时间和负担的自发波动.
主要方法:
- 对于非永久性AF患者 (不包括节律控制) 的2018-2023年ILR查询的回顾性审查.
- AF 插曲的持续时间被分为<6,6-24或>24小时.
- AF负担被分类为<2%,2%-11.4%,或>11.4%.
主要成果:
- 在任何时间最长的AF发作为6-24小时或24小时以上的患者中,分别只有12%和15%的询问显示出这些范围内的发作;其余的发作为6小时以下.
- 对于AF负担,在最大负担为2%-11.4%或>11.4%的患者中,分别只有11%和17%的询问符合这些标准;大多数 (65%) 显示负担<2%.
结论:
- 在ILR患者中,AF持续时间和负荷的显著自发波动是常见的.
- 大多数询问显示AF指标低于既定值,即使在以前已经超过值的患者中也是如此.
- 需要进一步的研究来确定这些波动是否会影响抗凝策略.

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...

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...

01:28Mechanism of Cardiac Arrhythmias
900
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.
