摘要翻译：
记录高质量单通道心电的可穿戴设备等新技术的发展，为更大人群的心电筛查，尤其是房颤筛查提供了契机。本研究的主要目标是开发一种用于正常窦性心律(NSR)、心房颤动(AF)、其他心律(O)和单通道短ECG段（9-60秒）噪声的自动分类算法。为此，采用信号质量指数(SQI)和稠密卷积神经网络相结合的方法。利用训练数据集对两个卷积神经网络(CNN)模型（接受15秒心电的主模型和处理9秒短心电的次模型）进行训练。如果记录被SQI确定为低质量，则立即将其归类为噪声。否则，它被转换为时频表示，并与CNN分类为NSR、AF、O或噪声。在最后一步，基于特征的后处理算法将节奏分为NSR或O,以防CNN模型对两者的区分不确定。Phymonet/CINC挑战的官方阶段在盲测试集上取得的最佳结果为0.80(NSR、AF和O的F1分别为0.90、0.80和0.70）。

英文摘要：
  The development of new technology such as wearables that record high-quality single channel ECG, provides an opportunity for ECG screening in a larger population, especially for atrial fibrillation screening. The main goal of this study is to develop an automatic classification algorithm for normal sinus rhythm (NSR), atrial fibrillation (AF), other rhythms (O), and noise from a single channel short ECG segment (9-60 seconds). For this purpose, signal quality index (SQI) along with dense convolutional neural networks was used. Two convolutional neural network (CNN) models (main model that accepts 15 seconds ECG and secondary model that processes 9 seconds shorter ECG) were trained using the training data set. If the recording is determined to be of low quality by SQI, it is immediately classified as noisy. Otherwise, it is transformed to a time-frequency representation and classified with the CNN as NSR, AF, O, or noise. At the final step, a feature-based post-processing algorithm classifies the rhythm as either NSR or O in case the CNN model's discrimination between the two is indeterminate. The best result achieved at the official phase of the PhysioNet/CinC challenge on the blind test set was 0.80 (F1 for NSR, AF, and O were 0.90, 0.80, and 0.70, respectively).
