[Electrocardiography in women with angina pectoris during physical exertion]

Comparative study was conducted of ECG changes during an attack of angina pectoris induced by physical exertion on a bicycle ergometer in 74 females and 100 males suffering from angina pectoris. It is shown that with a similar clinically determined severity of angina pectoris, tolerance to physical exertion is significantly lower in females than in males. Essential differences were also revealed in the ECG changes during an anginose attack. The data obtained are evidence that the approach to the appraisal of the results of load tests in ischemic disease of the heart in females should evidently differ from that in males.
