Handheld ECG event recorders are useful for rhythm monitoring but only record a single lead, which may limit interpretation. We sought to investigate if a multi-lead ECG may be reconstituted using this device, and aimed to evaluate diagnostic accuracy.
A commercially-available handheld bipolar ECG event recorder was used to reconstruct a 9-lead ECG (leads I, II and III, V1-6). Tracings were analyzed independently by a cardiologist and a fellow.
A total of 52 patients were evaluated. Accuracy was excellent (85-98%) for identifying atrial fibrillation, atrioventricular block, bundle branch block and left ventricular hypertrophy, but lower (77-88%) for ST-segment changes and prolonged QTc.
A 9-lead ECG can be reconstituted using a handheld single-lead ECG event recorder, and provides good diagnostic accuracy for common findings.
手持式心电图事件记录仪有助于心律监测，但仅记录单导联，这可能会限制解读。我们试图研究是否可用该设备重建多导联心电图，并旨在评估诊断准确性。
使用市售的手持式双极心电图事件记录仪重建9导联心电图（I、II、III、V1 - 6导联）。心电图由一名心脏病专家和一名研究员独立分析。
共评估了52例患者。识别心房颤动、房室传导阻滞、束支传导阻滞和左心室肥厚的准确性极佳（85 - 98%），但对ST段改变和QTc延长的准确性较低（77 - 88%）。
使用手持式单导联心电图事件记录仪可重建9导联心电图，对常见发现具有良好的诊断准确性。
