The PTB Diagnostic ECG Database
收藏资源简介:
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.
本数据集收录的心电图(Electrocardiogram, ECG)均采用非商用PTB原型记录仪采集,该设备的技术参数如下: 1. 16路输入通道,其中14路用于心电图采集、1路用于呼吸监测、1路用于线路电压监测; 2. 输入电压范围:±16 mV,补偿偏移电压最高可达±300 mV; 3. 输入电阻:100 Ω(直流); 4. 分辨率:16位,每最低有效位(Least Significant Bit, LSB)对应0.5 μV,即每mV对应2000个模数转换(Analog-to-Digital, A/D)单位; 5. 带宽:0~1 kHz,所有通道同步采样; 6. 短路输入时的噪声电压:峰峰值(peak-to-peak, pp)最大为10 μV,均方根值(root mean square, RMS)为3 μV; 7. 支持皮肤电阻在线记录,且可在信号采集过程中同步记录噪声水平。 本数据库共收录290名受试者的549条记录:受试者年龄跨度为17至87岁,平均年龄57.2岁;其中男性209名,平均年龄55.5岁,女性81名,平均年龄61.6岁;另有1名女性及14名男性受试者的年龄信息未被记录。每名受试者对应1至5条记录。
