Are there any 12-lead (diagnostic) ECGs in PhysioBank?
The PTB Diagnostic ECG Database contains 549 twelve-lead ECGs from 294 subjects. Most of these ECGs are two minutes in duration. (They also include simultaneously recorded Frank XYZ leads.) The St.-Petersburg Institute of Cardiological Technics 12-lead Arrhythmia Database contains 75 twelve-lead ECGs from 32 subjects. Each recording is 30 minutes in duration. The NHLBI maintains a registry of diagnostic ECG databases. The CSE Database and the 12-lead ECG Library may also be of interest.
