[Changes in the continuous electrocardiogram during the exercise stress test in women with angina pectoris and normal coronarography findings].

Ischaemic cardiac disease is usually diagnosed in patients with obstruent coronary arteries. However, it is also found in subjects with normal coronary arteries. Ten female patients, aged 30-40 years, with angina pectoris and normal coronary findings, were studied. Electrocardiographic changes were studied during physical tests and 24-hour electrocardiography. The findings suggested a mixed form of angina pectoris with both vasospasm and obstruent prearterioles.
