Why the study?
Do different ECG interpretation programs differ in their measurements of PR, QRS, and QT intervals?
Do different ECG interpretation programs differ in their measurements of PR, QRS, and QT intervals?
Clinicians should be aware that automated ECG interpretation programs can have systematic differences and potentially large errors in difficult cases.
Clinicians should verify automated ECG intervals in difficult cases; leaves open standardization and validation needs across programs.
When reading digital ECGs, users should be aware that small systematic differences exist between programs and that there may be large clinically important errors in difficult cases.
