Apnea-ECG Database

The data consist of 70 records, divided into a learning set of 35 records (a01 through a20, b01 through b05, and c01 through c10), and a test set of 35 records (x01 through x35), all of which may be downloaded from this page. Recordings vary in length from slightly less than 7 hours to nearly 10 hours each. Each recording includes a continuous digitized ECG signal, a set of apnea annotations (derived by human experts on the basis of simultaneously recorded respiration and related signals), and a set of machine-generated QRS annotations (in which all beats regardless of type have been labeled normal). In addition, eight recordings (a01 through a04, b01, and c01 through c03) are accompanied by four additional signals (Resp C and Resp A, chest and abdominal respiratory effort signals obtained using inductance plethysmography; Resp N, oronasal airflow measured using nasal thermistors; and SpO2, oxygen saturation).

本数据集共包含70条记录，分为训练集（35条记录，编号为a01至a20、b01至b05以及c01至c10）与测试集（35条记录，编号为x01至x35），所有记录均可从本页面下载。每条记录的时长介于略少于7小时至近10小时之间。每份记录均包含连续数字化心电图（ECG）信号、一组呼吸暂停标注（由人类专家基于同步记录的呼吸及相关信号推导得出），以及一组机器生成的QRS波标注（其中所有心跳无论类型均被标记为正常）。此外，其中8条记录（a01至a04、b01以及c01至c03）附带4种额外信号：Resp C与Resp A分别为采用电感体积描记法获取的胸部、腹部呼吸努力信号；Resp N为采用鼻热敏电阻测量的口鼻气流信号；SpO2为血氧饱和度信号。
