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).

本数据集包含70条记录，分为包含35条记录的学习集（a01至a20，b01至b05，以及c01至c10）和包含35条记录的测试集（x01至x35），所有记录均可从本页面下载。记录长度各异，介于略少于7小时至近10小时不等。每条记录均包含一个连续的数字化心电图信号、一组由人类专家基于同时记录的呼吸及相关信号得出的呼吸暂停标注，以及一组由机器生成的QRS标注（其中无论何种类型的心跳均被标注为正常）。此外，共有八条记录（a01至a04，b01，以及c01至c03）伴随四种额外的信号：Resp C和Resp A，利用电感体积描记法获得的胸部和腹部呼吸用力信号；Resp N，通过鼻温敏电阻测量的鼻咽部气流；以及SpO2，测量血氧饱和度。
