Atrial fibrillation (AF) is the leading cause of stroke. The European Society of Cardiology (ESC) advises opportunistic AF screening among patients aged ≥ 65 years. Considering this, the aim herein, was compare the feasibility of two different systems of smartphone-based electrocardiogram (ECG) recordings to identify AF among those without a previous arrhythmia history.
Prospective AF screening was conducted at six pharmacies using Kardia Mobile and Hartmann Veroval 2 in 1. A single-lead ECG was acquired by the placement of fingers on the pads. A cardiologist evaluated findings from both devices.
Atrial fibrillation was identified in 3.60% and previously unknown AF was detected in 1.92% of the study participants. Sensitivity and specificity of the Kardia application in detecting AF were 66.7% (95% confidence interval [CI] 38.4-88.2%) and 98.5% (95% CI 96.7-99.5%), and for Veroval 10.0% (95% CI 0.23-44.5%) and 94.96% (95% CI 92.15-96.98%), accordingly. Inter-rater agreement was k = 0.088 (95% CI 1.59-16.1%).
Mobile devices can detect AF, but each finding must be verified by a professional. The Kardia application appeared to be more user-friendly than Veroval. Cardiovascular screening using mobile devices is feasible at pharmacies. Hence it might be considered for routine use.
心房颤动（AF）是中风的主要原因。欧洲心脏病学会（ESC）建议在年龄≥65 岁的患者中进行机会性 AF 筛查。考虑到这一点，本研究旨在比较两种基于智能手机的心电图（ECG）记录系统在识别无先前心律失常史的人群中 AF 的可行性。
在六家药店使用 Kardia Mobile 和 Hartmann Veroval 2 in 1 进行前瞻性 AF 筛查。将手指放在电极片上获取单导联心电图。由一名心脏病专家评估两种设备的结果。
研究参与者中，3.60%的人被诊断为 AF，1.92%的人检测到以前未知的 AF。Kardia 应用程序检测 AF 的敏感性和特异性分别为 66.7%（95%置信区间[CI] 38.4-88.2%）和 98.5%（95% CI 96.7-99.5%），Veroval 的敏感性和特异性分别为 10.0%（95% CI 0.23-44.5%）和 94.96%（95% CI 92.15-96.98%）。观察者间一致性为 k = 0.088（95% CI 1.59-16.1%）。
移动设备可以检测 AF，但每个发现都必须由专业人员验证。Kardia 应用程序似乎比 Veroval 更易于使用。在药店使用移动设备进行心血管筛查是可行的。因此，它可以考虑常规使用。
