Why the study?
Does a computer-analysed 3-lead ECG accurately predict coronary artery disease and myocardial ischaemia compared to a conventional 12-lead ECG in patients undergoing coronary arteriography?

Comparable accuracy in cross-sectional data supports further 3-lead ECG evaluation; leaves open prospective validation before clinical adoption.
Does a computer-analysed 3-lead ECG accurately predict coronary artery disease and myocardial ischaemia compared to a conventional 12-lead ECG in patients undergoing coronary arteriography?
A computer-analysed 3-lead ECG provides comparable diagnostic accuracy to a cardiologist-interpreted 12-lead ECG for detecting coronary artery disease.
