To validate the sensitivity and specificity of the Zenicor One handheld ECG device for detection of atrial fibrillation in an outpatient clinical setting. Patients attending outpatient clinics at Danderyd Hospital ( = 220) were examined with one lead handheld ECG immediately after standard care 12‑lead ECG recording. Twelve recordings were excluded (atrial flutter or pacing) or missing. The recordings were dichotomously categorized as “atrial fibrillation” or “not atrial fibrillation” by two senior cardiologists. In cases of diverging interpretations, a third senior cardiologist had the deciding vote. Sensitivity and specificity in diagnosing atrial fibrillation was calculated with 12‑lead ECG as gold standard. In a health-care outpatient setting, Zenicor One handheld ECG had high sensitivity and specificity for detection of atrial fibrillation when compared with 12‑lead ECG.

手持式单导联心电图在门诊环境中检测心房颤动的敏感性和特异性

验证 Zenicor One 手持式心电图设备在门诊临床环境中检测心房颤动的敏感性和特异性。在 Danderyd 医院门诊就诊的患者 (= 220) 在标准护理 12 导联心电图记录后立即使用一导联手持式心电图进行检查。十二个记录被排除（心房扑动或起搏）或丢失。两位资深心脏病专家将这些录音分为“心房颤动”或“非心房颤动”两类。如果出现不同的解释，则由第三位资深心脏病专家进行决定性投票。使用 12 导联心电图作为金标准计算诊断心房颤动的敏感性和特异性。在医疗保健门诊环境中，与 12 导联心电图相比，Zenicor One 手持式心电图在检测心房颤动方面具有较高的灵敏度和特异性。
