在使用Kardia移动心电图装置的65岁及以上个体中,针对心房动 (AF) 进行机会性查是可行的. 这种方法在2.5%的参与者中发现了新的AF病例,有助于预防相关并发症.
科学领域:
- 心脏病学 心脏病学
- 数字健康数字健康
- 公共卫生 公共卫生
背景情况:
- 未经治疗的心房动 (AF) 显著增加患病和死亡风险.
- 建议在65岁及以上的个人进行机会性AF查,以预防AF相关的并发症.
研究的目的:
- 评估使用Kardia移动心电图装置 (MED) 进行AF查的可行性.
- 通过荷兰的选择性人口查来确定新发现的AF病例的发病率.
主要方法:
- 从养老院,公共活动和一般实践中招募65岁以上没有AF病史的个人.
- 使用Kardia MED记录智能手机心电图 (sECGs) 并计算CHA-VASc分数.
- 通过自动算法对sECG进行分类 (鼻节律,AF,未分类),对所有记录进行盲目专家审查.
主要成果:
- 在2168名接受查的参与者中,有2.5%的参与者新发现了AF,大多数人不知道他们的情况,并且具有高的CHA2DS2-VASc分数.
- 卡迪亚MED算法的未分类率为12.2%,但95.5%可以被专家解释.
- 除了未分类的结果外,该设备在对专家解释的AF检测方面显示了99.8%的负预测值和60.0%的正预测值.
结论:
- 使用Kardia MED查心房动是一种可行的方法.
- 这种查方法发现了2.5%的新的AF病例,突出了其早期检测的潜力.
- 建议对算法结果进行专家解释,特别是对于AF和未分类读数,以获得最佳准确性.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
