[Effort electrocardiogram in woman].
On the basis of 150 results on patients who underwent an ECG at submaximal exercise, selective coronary arteriography and cine-arteriography, this study has established that: -- certain elecerographic criteria of coronary insufficiency which have a high predictive value in males (a "near ischeamic" appearance, an J depression at or above 4 mm) are not applicable to the female; -- where an ECG tracing which is abnormal at rest becomes normal on exercise, then in both males and females there is a healthy coronary tree; -- the incidence of false-positives is 22.9%, which is 4 times that found in males; -- propranolol (60 mg orally) returns these pseudo-ischaemic changes in the resting and exercise ECG to normal and affords a simple method of identifying the false positives.
