PTB Diagnostic ECG Database Dataset

The ECGs in this collection were obtained using a non-commercial, PTB prototype recorder with the following specifications:

16 input channels, (14 for ECGs, 1 for respiration, 1 for line voltage)
Input voltage: ±16 mV, compensated offset voltage up to ± 300 mV
Input resistance: 100 Ω (DC)
Resolution: 16 bit with 0.5 μV/LSB (2000 A/D units per mV)
Bandwidth: 0 - 1 kHz (synchronous sampling of all channels)
Noise voltage: max. 10 μV (pp), respectively 3 μV (RMS) with input short circuit
Online recording of skin resistance
Noise level recording during signal collection
The database contains 549 records from 290 subjects (aged 17 to 87, mean 57.2; 209 men, mean age 55.5, and 81 women, mean age 61.6; ages were not recorded for 1 female and 14 male subjects). Each subject is represented by one to five records. There are no subjects numbered 124, 132, 134, or 161. Each record includes 15 simultaneously measured signals: the conventional 12 leads (i, ii, iii, avr, avl, avf, v1, v2, v3, v4, v5, v6) together with the 3 Frank lead ECGs (vx, vy, vz). Each signal is digitized at 1000 samples per second, with 16 bit resolution over a range of ± 16.384 mV. On special request to the contributors of the database, recordings may be available at sampling rates up to 10 KHz.

Within the header (.hea) file of most of these ECG records is a detailed clinical summary, including age, gender, diagnosis, and where applicable, data on medical history, medication and interventions, coronary artery pathology, ventriculography, echocardiography, and hemodynamics. The clinical summary is not available for 22 subjects.

本数据集中收录的心电图（ECG）记录均采用非商业化的PTB原型记录仪获取，其技术参数如下：
16个输入通道（其中14个用于心电图，1个用于呼吸，1个用于线路电压），输入电压：±16毫伏，补偿偏移电压可达±300毫伏，输入阻抗：100欧姆（直流），分辨率：16位，每位0.5微伏（对应2000个模数转换单位每毫伏），带宽：0至1千赫兹（同步采样所有通道），噪声电压：最大10微伏（峰峰值），短路输入时分别为3微伏（均方根值）。在线记录皮肤电阻，信号采集期间的噪声水平记录。数据库包含290名受试者（年龄介于17至87岁之间，平均年龄57.2岁；男性209名，平均年龄55.5岁，女性81名，平均年龄61.6岁；1名女性和14名男性受试者的年龄未记录；每个受试者由1至5条记录表示。编号为124、132、134或161的受试者不存在。每条记录包括15个同时测量的信号：常规的12导联心电图（i、ii、iii、avr、avl、avf、v1、v2、v3、v4、v5、v6）以及3个Frank导联心电图（vx、vy、vz）。每个信号以每秒1000个样本的速率进行数字化，16位分辨率，范围在±16.384毫伏之间。在数据库贡献者的特别要求下，记录可能以高达10千赫兹的采样率提供。
大多数心电图记录的头部（.hea）文件中包含详细的临床摘要，包括年龄、性别、诊断，以及相应情况下，医疗史、用药和干预措施、冠状动脉病理、心室造影、超声心动图和血流动力学数据。22名受试者的临床摘要不可用。
