Traditional long-term ECG monitoring systems have primarily been used by cardiologist. New remote and wearable easy-to-use devices have led to increased use of ECG recordings also outside cardiology clinics. The aims of this study were to assess the feasibility and diagnostic accuracy of interpretation of the one-lead ECG recordings from a patch ECG device (ECG247 Smart Heart Sensor system) by general practitioners (GP).
Norwegian GPs were invited to digitally assess 10 long-term ECG recordings with different arrhythmias performed by the ECG247 Smart Heart Sensor system. For all ECG examinations, the presence/absence of different arrhythmias was registered.
A total of 40 GPs accepted the invitation and assessed all the 10 long-term ECG recordings. All the tests were assessed as interpretable by all the GPs. Arrhythmias (atrial fibrillation/flutter, supraventricular tachycardia, and ventricular tachycardia) were correctly identified in most cases, with sensitivity of 98% (95% CI 95-99%), specificity of 75% (95% CI 68-82%), and diagnostic accuracy of 89% (85-92%). Incorrect automatic system algorithm interpretations were rarely corrected by the GPs.
GPs interpreted one-lead recordings by the ECG247 Smart Heart Sensor system with high diagnostic accuracy for common arrhythmias. However, in cases with rare arrhythmias, we recommend consulting a cardiologist to confirm the diagnosis before treatment is initiated. This trial is registered with NCT04700865.
传统的长期心电图监测系统主要由心脏病专家使用。新型远程且易于使用的可穿戴设备使得心电图记录在心脏病诊所之外的应用也有所增加。本研究的目的是评估全科医生（GP）对贴片式心电图设备（ECG247智能心脏传感器系统）的单导联心电图记录进行解读的可行性和诊断准确性。
邀请挪威的全科医生对ECG247智能心脏传感器系统记录的10份伴有不同心律失常的长期心电图进行数字化评估。对于所有心电图检查，记录不同心律失常的有无。
共有40名全科医生接受邀请并评估了所有10份长期心电图记录。所有全科医生均认为所有测试结果均可解读。大多数情况下，心律失常（心房颤动/扑动、室上性心动过速和室性心动过速）能够被正确识别，敏感性为98%（95%可信区间95 - 99%），特异性为75%（95%可信区间68 - 82%），诊断准确性为89%（85 - 92%）。全科医生很少纠正自动系统算法的错误解读。
全科医生对ECG247智能心脏传感器系统的单导联记录进行解读时，对常见心律失常具有较高的诊断准确性。然而，对于罕见心律失常的情况，我们建议在开始治疗前咨询心脏病专家以确诊。本试验已在ClinicalTrials.gov注册，注册号为NCT04700865。
