[Characteristics and significance of cardiodynamic disorders in patients with stenocardia and a history of myocardial infarction].
To judge of the contractile function of the heart polycardiography and apical cardiography were used to study a male population aged 40-49 years and 57 patients up to 50 years with ischaemic heart disease (IHD). The investigations were made at rest and after a tread-mill test. Patients with IHD were divided into 3 groups: those who had myocardial infarction from 6 months to 3 years with high and low tolerance to exercise and persons with angina pectoris. All patients with IHD were found to have extension of the isometric contraction on the polycardiogram and enhanced amplitude of the atrial wave in relation to the main systolic wave of the apexcardiogram, and also decreased tolerance to exercise. Cardiodynamic disorders in patients with angina pectoris were manifest as clearly as in many patients who had had myocardial infarction.
