The value of the effort electrocardiogram.
The most useful single predictor of future coronary events, but independent of other risk factors, is an effort electrocardiogram indicating ischaemia. The double Master's test as currently used is apt to fail in this respect in 46% of patients with abnormal hearts. The history of stress testing is outlined and it is concluded that treadmill techniques using the S-T segment index represent a much-needed advance on other methods. A small percentage of false positives and false negatives still remains, even with the most sophisticated computer-assisted techniques, and the reasons for this are discussed.
