Distinguishing Ischemic from Non-Ischemic ST Changes - The PhysioNet Computing in Cardiology Challenge 2003

For the fourth annual PhysioNet/Computers in Cardiology Challenge, we propose a provocative question of considerable clinical interest: Is it possible to tell the difference between transient ST changes in the ECG that are due to myocardial ischemia…
