The exercise electrocardiograms and coronary arteriograms of 119 patients were examined to evaluate the significance of dysrhythmias associated with exercise testing. The overall incidence of dysrhythmias before, during and after exercise was 19 percent. The frequency of dysrhythmias was greater (26 percent) in patients with a positive exercise test than in patients with a negative exercise test (11 percent). The results of the exercise tests were correlated with coronary arteriographic findings to detect false positive and false negative results. There was no significant statistical difference in the frequency of dysrhythmias between patients who responded positively and those who responded negatively to exercise. The timing of the dysrhythmia (before, during or after exercise) was not different in the 2 groups. We conclude that dysrhythmias associated with exercise testing should raise the index of suspicion of underlying coronary artery disease but should not be used as a criterion for a positive test.
