Circulation:从标准12导联ECG检查中精准识别QT间期延长的人工智能算法!

通过AI支持的mECG设备可能为多种临床环境中获得性和先天性长QT间期综合征的筛查提供了一种经济有效的方法

心率校正的QT间期(QTc)延长,无论继发于药物、遗传因素(包括先天性长QT间期综合征),还是继发于系统性疾病(包括新冠肺炎[COVID-19]),都可导致室性心律失常和心源性猝死。QTc评估和监测很大程度上依赖于12导联心电图。

近日,在《循环》杂志上发表的一篇最新研究,Giudicessi等研究人员尝试建立并验证了支持人工智能(AI)的12导联心电图算法,以检测QTc,然后在复极异常的人群中对移动ECG(mECG)设备获取的描迹进行前瞻性测试。

采用了来自538200位患者的160万份12导联ECG检查数据,开发并验证了一个深度神经网络(DNN),以采用心脏病专家过度读取的QTc值作为“黄金标准”来预测QTc。此外,还在686例遗传性心脏病(50%存在长QT综合征)患者中前瞻性地测试了该DNN检查临床相关QTc延长的能力。

不同方法预测QTc值的对比

在验证样本中,在专家过度解读的和DNN预测的QTc值之间观察到了很强的一致性(-1.76±23.14 ms)。与此相似的,在遗传性心脏病患者群中的结果也在预期内,DNN根据mECG轨迹预测的QTc值与由QT专家和商业核心ECG实验室解读的12导联ECG结果的差异也很小

DNN检测QTc的表现

当应用于mECG轨迹时,DNN检测QTc值≥500 ms的能力在曲线下的面积、灵敏度和特异性分别为0.97、80.0%和94.4%

综上,该研究开发的人工智能DNN可准确识别标准12导联ECG检查的QTc。通过AI支持的mECG设备可能为多种临床环境中获得性和先天性长QT间期综合征的筛查提供了一种经济有效的方法。
