The PTB Diagnostic ECG Database

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.
