摘要
目的评价可穿戴心电监测设备在临床环境下检测心律失常(窦性心律、室性早搏、房性早搏和心房颤动)及心率的准确性。方法招募受试者321例(875条心电记录),其中男146例(531条心电记录),女175例(344条心电记录)。采用可穿戴心电监测设备采集心电图,检测心律失常与心率,并与基于12导联心电图机的医生临床诊断结果(作为诊断心律失常与检测心率的金标准)进行对比。对所有受试者进行两种检测方法的准确性及一致性评价,包括准确率、敏感性、特异性、F1得分、受试者工作特征曲线的曲线下面积(area under curve,AUC)、Bland-Altman一致性分析、平均绝对误差和相关图。结果可穿戴心电监测设备识别心律失常的AUC为0.98,准确率为0.98,敏感性为0.96,特异性为0.99,F1得分为0.96;可穿戴心电监测设备检测的心率和心电图机检测的心率相关性强,总的相关系数为0.84(P<0.01)。Bland-Altman一致性分析显示,两种方法的均值差值为-0.97次/min,均标准差为8.02次/min,95%置信区间为-16.69~14.75,属于可接受水平。结论可穿戴心电监测设备能够较准确地检测心律失常和心率。
Objective To assess the accuracy of wearable electrocardiogram(ECG)monitoring device for detecting arrhythmias(sinus rhythm,premature ventricular contraction,premature atrial contraction,and atrial fibrillation),and heart rate in a clinical setting.Methods A total of 321 volunteers(875 ECG records)participated in this study,including 146 males(531 ECG records)and 175 females(344 ECG records).A wearable ECG monitoring device was employed to record ECGs for detecting arrhythmias and heart rate.The detection results were compared with physicians'clinical diagnostic results based on 12-lead ECG machine(regraded as the gold standard for diagnosing arrhythmias and detecting heart rate).Accuracy and consistency evaluation of the two detection methods was conducted in all the subjects,including accuracy,sensitivity,specificity,F1 score,area under curve(AUC)of the receiver operating characteristic curve,Bland-Altman consistency analysis,mean absolute error,and correlogram.Results Regarding arrhythmia identification,wearable ECG monitoring device exhibits impressive performance metrics,with an AUC of 0.98,accuracy of 0.98,sensitivity of 0.96,specificity of 0.99,and an F1 score of 0.96.In terms of heart rate monitoring,a robust correlation between the wearable ECG monitoring equipment and the ECG machine is evident,with a substantial total correlation coefficient of 0.84(P<0.01).Bland-Altman consistency analysis reveals that the two methods display a mean difference of-0.97 times per minute,a mean standard deviation of 8.02 times per minute,and a 95% confidence interval ranging from-16.69 to 14.75 within an acceptable level.Conclusion Wearable ECG monitoring device can accurately detect arrhythmias and heart rate.
