MyDiagnostick (MDK) is a novel portable ECG recorder. We conducted this study to evaluate its role in screening for atrial fibrillation (AF). The device is a cylindrical rod with metallic electrodes at both ends recording electrocardiogram (ECG) when both electrodes are held. Individuals were requested to hold the device for approximately 15 s, the device was then connected to a laptop (with proprietary software downloaded) and analysed. Anonymised ECGs were stored for further analysis. A total of 855 ECGs were recorded and analysed offline by two arrhythmia specialists assessing ECG quality, in particular the level of noise. A noise score (NS) was devised regarding ECG quality. Seven individuals were found with unknown AF (0,8%). In general ECG quality was good and rhythm diagnosis was certain with total interobserver agreement. The MDK provided a rapid and accurate rhythm analysis and has potential implications in preventing ischaemic cardio-embolic stroke.
MyDiagnostick（MDK）是一款新型便携式心电图记录仪。我们开展这项研究以评估其在心房颤动（AF）筛查中的作用。该设备是一根圆柱形棒，两端带有金属电极，当握住两个电极时可记录心电图（ECG）。要求受试者握住该设备约15秒，然后将设备连接到笔记本电脑（已下载专有软件）并进行分析。匿名的心电图被存储以供进一步分析。总共记录了855份心电图，并由两名心律失常专家进行离线分析，评估心电图质量，尤其是噪声水平。针对心电图质量设计了一个噪声评分（NS）。发现7例不明心房颤动患者（0.8%）。总体而言，心电图质量良好，节律诊断明确，观察者间完全一致。MDK提供了快速准确的节律分析，对预防缺血性心源性栓塞性中风具有潜在意义。
