MyDiagnostick is an atrial fibrillation (AF) screening tool that has been validated in the Caucasian population in the primary care setting.
In our study, we compared MyDiagnostick with manual pulse check for AF screening in the community setting.
In our cohort of 671 candidates from a multi-ethnic Asian population, AF prevalence was found to be 1.78%. Of 12 candidates, 6 (50.0%) had a previous history of AF and another 6 (50.0%) were newly diagnosed with AF. Candidates found to have AF during the screening were older (72.0 ± 11.7 years vs. 56.0 ± 13.0 years, P < 0.0001) and had a higher CHADSVASC risk score (2.9 ± 1.5 vs. 1.5 ± 1.1, P = 0.0001). MyDiagnostick had a sensitivity of 100.0% and a specificity of 96.2%. In comparison, manual pulse check had a sensitivity of 83.3% and a specificity of 98.9%.
MyDiagnostick is a simple AF screening device that can be reliably used by non-specialist professionals in the community setting. Its sensitivity and specificity are comparable and validated across various studies performed in different population cohorts.
MyDiagnostick 是一种心房颤动（AF）筛查工具，已在初级保健环境中的白种人群中得到验证。
在我们的研究中，我们将 MyDiagnostick 与手动脉搏检查进行了比较，以进行社区环境中的 AF 筛查。
在我们来自多民族亚洲人群的 671 名候选者队列中，AF 的患病率为 1.78%。在 12 名候选者中，有 6 名（50.0%）有 AF 的既往病史，另有 6 名（50.0%）新诊断为 AF。在筛查期间发现患有 AF 的候选者年龄较大（72.0±11.7 岁 vs. 56.0±13.0 岁，P<0.0001），且 CHADSVASC 风险评分较高（2.9±1.5 vs. 1.5±1.1，P=0.0001）。MyDiagnostick 的敏感性为 100.0%，特异性为 96.2%。相比之下，手动脉搏检查的敏感性为 83.3%，特异性为 98.9%。
MyDiagnostick 是一种简单的 AF 筛查设备，可由社区环境中的非专业人员可靠使用。其敏感性和特异性在不同人群队列中进行的各种研究中是可比且经过验证的。
